NoteNote

functions correctly. Any damaged or defective items must be returned in their original packing material with the supplied accessories.

1.2 MODEL IDENTIFICATION

Meter: There are two models for the meter:

HI 9829: Portable multiparameter meter HI 98290: Portable multiparameter meter with GPS

Probe: There are two base models of multiparameter probes:

HI 7609829: Standard multiparameter probe HI 7629829: Multiparameter probe with autonomous logging

capability

All meters and probes are fully compatible with each other, and all available measurement sensors can be used on both probe models.

Different combinations of meters, probes, sensors and accessories can be ordered either in predefined configurations or individually. See Appendix D for ordering configurations.

For example, ordering codes of probes follow: HI 7609829/X is a HI 7609829 probe with X meter cable for pH/pH+ORP/

ISE, D.O., EC, temperature sensors with a short probe shield HI 7619829/X is a HI 7609829 probe with X meter cable for pH/pH+ORP/

ISE, D.O., EC+turbidity, temperature sensors with a long probe shield HI 7629829/X is a HI 7629829 logging probe with X meter cable for pH/

pH+ORP/ISE, D.O., EC, temperature sensors with a short probe shield HI 7639829/X is a HI 7629829 logging probe with X meter cable for pH/

pH+ORP/ISE, D.O., EC+turbidity, temperature sensors with a long probe shield

1.3 GENERAL DESCRIPTION HI 9829 is a portable logging multiparameter system that monitors up to 14

different water quality parameters (7 measured, 7 calculated). The microprocessor-based intelligent multisensor probe allows measurement of

many water quality parameters such as pH, ORP, turbidity, dissolved oxygen,

conductivity, chloride, nitrate, ammonium and temperature with data logging. The system is easy to setup and easy to use.

The HI 98290 with GPS option has a built-in 12 channel GPS receiver and antenna that guarantees a position accuracy of 10 m (30 ft). Measurements from specific locations are tracked with detailed coordinate information that can be viewed immediately on the display. GPS information can be transferred to a PC using HANNA’s HI 929829 software. GPS information can also be viewed using a GPS mapping software such as Google™ Maps. Clicking on visited locations using a mapping software displays the measurement information.

All HI 9829 are equipped with Fast Tracker™ an invaluable tool for associating measurements with their locations. HANNA’s exclusive Fast Tracker™—T.I.S. (Tag ID System) uses

iButton®s that can be installed at any number of sampling sites.

The HI 9829 features a graphic, backlit display that automatically sizes the digits to fit the screen with on-screen graphing capability. Each parameter is fully configurable.

HI 9829 was designed to withstand harsh environments and is the ideal solution for field measurements of lakes, rivers and sea. The meter meets IP67 standards (30 minute immersion at a depth of 1 m) and the multisensor probe meets IP68 standards (continuous immersion in water). Settings and logged data can be protected with a passcode to avoid unauthorized modifications and context-sensitive help is always available.

Main features of the HI 9829 system:

• Rugged meter and probe

• Easy to use

• Measure up to 16 parameters and display of up to 12 parameters

• Tracking of measurement locations with GPS (optional)

• Waterproof protection (IP67 for the meter and IP68 for the probe)

• Exclusive Fast Tracker™—T.I.S. (Tag ID System)

• Graphic LCD with backlight

• Built-in barometer for D.O. concentration compensation

METER BATTERY LIFE

The power consumption of the HI 9829 multiparameter system is dependent on three things:

1. The measurement system configuration (probe type, sensor configuration)

2. The meter configuration (logging interval, GPS and backlight use)

3. The battery type (alkaline or rechargeable). Note: Alkaline batteries have two times the expected life.

The following table estimates the meter’s battery life connected to a HI 76X9829 probe with backlight off. The logging interval only affects meter

battery life when GPS Powersave mode is used (units with GPS). (Note: GPS and backlighting use consume the most power). The table variables are GPS, battery selection and parameter selection. Note: When a HI 7629829 logging probe is connected to a meter, it uses the meter’s power.

4.2 SENSOR PREPARATION / ACTIVATION

4.2.1 pH Preparation

Remove the shipping cap from the pH sensor. If the shipping cap does not contain any liquid, pour HI 70300 into shipping cap, place it back on the sensor and soak for at least 1/2 hour before use. If HI 70300 is not available, pH 4.01 buffer may be substituted.

4.2.2 ORP Activation

For improved redox measurements, the surface of the sensor must be clean and smooth. A pretreatment procedure should be performed to ensure quick response.

The pretreatment of the sensor is determined by the pH and the ORP potential values of the sample. Use the table below to determine the treatment required.

First locate the typical sample pH. If the corresponding ORP value (mV) is higher than the values in the table below, an oxidizing pretreatment is necessary. If the value is lower, a reducing pretreatment is necessary.

For reducing pretreatment: immerse the electrode for at least five minutes in HI 7091.

For oxidizing pretreatment: immerse the electrode for at least five minutes in HI 7092.

4.2.3 D.O. Sensor Activation

The D.O. probe is shipped dry. To prepare the sensor for use:

• Remove the black & red plastic shipping cap and discard.

• Insert the supplied O-ring in to the membrane cap.

• Rinse the membrane with some electrolyte solution. Refill with clean electrolyte.

Gently tap the black membrane cap to dislodge air bubbles. To avoid damaging the membrane, do not touch it with your fingers or directly tap the membrane.

• With the sensor facing down screw the membrane cap counterclockwise to the

end of the threads. Some electrolyte will overflow.

• Rinse outside of sensor with deionized water.

• Invert sensor and inspect. There should be no bubbles or debris between the

membrane and sensor body.

4.2.4 EC and EC/Turbidity Sensor Preparation

The EC and EC/Turbidity sensors do not need to be soaked or hydrated before use. Use the small brush included in the probe maintenance kit to clean and loosen any debris before using.

4.2.5 Ammonium Sensor Preparation

Remove the shipping cap and inspect sensor. Verify no air pockets have developed near the ceramic junction during shipping. Hold the sensor at the connector and shake it down (like a mercury thermometer). Condition the sensor by soaking it in a small amount of

4.3 SENSOR INSTALLATION

The HI 76x9829 can support 3 different sensors: Connector 1: pH, pH/ORP or ISE (Ammonium, Chloride, Nitrate), Connector 2: D.O., Connector 3: EC or EC/Turbidity.

To make installation easier, the sensors have color-coded caps and the sockets are identified with colored triangles.

NoteNote

Note The EC/Turbidity sensor with 9 pin connector does not have a

NoteNote

color-coded cap. It is always installed into the socket with three blue triangles.

For a correct installation:

• Grease the sensor O-ring with the lubricant found in the probe maintenance

kit. DO NOT SUBSTITUTE other grease/lubricants as it may cause the O-ring to swell.

• Insert the sensor into the correctly color coded opening while positioning the

connector key toward the center of the probe. Make sure the connector is seated correctly (the sensor will no longer move freely) before tightening the locking threads with your fingers.

• Continue to tighten the locking threads with the tool supplied in the mainte

nance kit until the sensor is secured tightly against the probe body.

• To protect the sensors, screw the protective shield onto the probe body.

• With the meter off, connect the probe to the DIN socket on the bottom of the

meter. Align the pins and key then push the plug into the socket. Tighten the knurled, threaded shell.

• Turn on the meter by pressing the ON/OFF key. The meter

should automatically recognize the installed sensors and identify them on the probe status screen. If you have an error message or the sensor is not recognized, reconnect the sensor(s) or probe and try again.

6.2.9 Absolute EC Resolution

Absolute conductivity displays the conductivity without temperature compensation. See 6.2.8 EC resolution for resolution details.

NoteNote

Note A small letter “A” added to the µS/cm or mS/cm unit refers to an abso-

NoteNote

lute conductivity value (i.e. a conductivity reading with no temperature compensation).

6.2.10 TDS Resolution

The user can configure the TDS resolution with one of the following options: Auto: the meter automatically chooses the range to optimize the measurement,

readings can be in ppt or ppm.

Auto ppt: the meter automatically chooses the range to optimize the measurement, readings will be in ppt only.

1 ppm, 0.001 ppt, 0.01 ppt, 0.1 ppt or 1 ppt: the meter will display the measurement with selected resolution. The default value is Auto.

6.2.11 GPS Format (optional)

Global positioning coordinates have three standard formats: XX°XX’XX.X’’, XX°XX.XXX’ and XX.XXXXX°. The selected format will be used in any screen where the GPS coordinates are displayed. The default format is XX°XX’XX.X.

6.3 PARAMETER COEFFICIENTS

6.3.1 EC Reference Temperature

This value is used for temperature compensated conductivity. All EC measurements will be referenced to the conductivity of a sample at this temperature. Press the softkey to select the desired option; 20 °C or at 25 °C. The default value is 25 °C.

6.3.2 EC Temperature Coefficient

The temperature coefficient Beta (β) is defined by

the following equation (using 25 °C as an example):

=EC

/(1+β(T

-25))

Beta is a function of the solution being measured. For freshwater samples Beta is approximately

1.90%/°C. If the actual temperature coefficient of your sample is known, press <Modify> to enter the value. To confirm press <Accept>. The value can be within 0.00 and 6.00%/°C. The default value is 1.90%/°C.

6.3.3 TDS Factor

TDS stands for total dissolved solids, and it is a calculated value based on the conductivity of the solution (TDS = factor x EC

). The TDS conver-

sion factor can be set from 0.00 to 1.00. A typical TDS factor for strong ionic solutions is 0.5, while for weak ionic solutions (e.g. fertilizers) is 0.7. Press <Modify> to enter the value, press <Accept> to confirm. The default value is 0.50.

6.4 AVERAGING

Averaging is a software filter to minimize sensor noise and provide more stable readings. Averaging is particularly useful to get a representative reading of the “average” value from flowing water. Averaging will affect all measurements (except Turbidity which can be set separately). This value should be kept low if you want a fast response. Press <Modify> to select the desired number of samples to average. This value can be set from 1 to 20 samples. The default value is 1.

NoteNote

Note Each reading takes 1 second, so when logging the first sample will be

NoteNote

delayed by a few seconds if averaging is used.

6.5 TURBIDITY AVERAGING

Turbidity averaging is software filter to minimize noise and provide more stable readings for turbidity. This parameter can be set without affecting the response times of other measurements.

As is the case for the other measurements, averaging is useful to provide representative readings of the “average” value in flowing water. Turbidity averaging can be set separately because the optical turbidity sensor is more strongly affected by bubbles and debris in the water stream than the other sensors.

Press <Modify> to enter the number of samples to average. The value can be set from 1 to 20 samples. The default value is 1.

Chapter 7 - CALIBRATION MODE

HI 9829’s calibration routines are accessed by highlighting “Calibration” and pressing <Select> from the main menu. Calibration is the process that standardizes the electrical or optical signals from the sensors to reagent standards of known value. Calibrations are intuitive and menu driven. All calibration data is stored in the non volatile probe memory, allowing probes to be connected to different meters without recalibration. There are two types of calibrations available: the “Quick calibration”, which is used for a single point calibration of pH, Conductivity, and/or Dissolved Oxygen and is handy for field work; and the “Single param. calibration” that allows each parameter to be calibrated individually. The user may also restore each parameter to a factory default calibration.

NoteNote

Note The password will be required if password protection is enabled.

NoteNote

To optimize measurements, it is advisable to establish the optimum calibration period required for the measurement environment. Calibration requirements vary with deployment conditions, for example very turbid biologically-active waters may require more frequent cleanings and calibrations than cleaner waters. General calibration guidelines are listed below:

• Set up a routine service schedule where measurement integrity is validated.

This is especially important for new installation sites or long deployments.

• Inspect sensor connectors for corrosion and replace damaged sensors.

• Inspect sensor o-rings for damage and if necessary replace and lubricate

with the grease found in the probe maintenance kit.

• Do not handle the sensing surfaces of the sensors.

• Avoid rough handling and abrasive environments that can scratch the

reactive surfaces of the sensors.

• Avoid long-term exposure of sensors to bright sunlight (especially chloride

ISEand turbidity sensor). If possible, calibrate in a shaded area.

• Discard standards after use. Do not return the used standards to the bottles

of “fresh” solution.

• For measurements across a temperature gradient (when water temperature

is drastically different from the standards), permit the sensors to reach thermal equilibrium before conducting calibrations or making measurements. The heat capacity of the probe is much greater than the air and the small beakers of calibration standards.

7.1 QUICK CALIBRATION

The quick calibration method provides a quick single point calibration for pH, conductivity and dissolved oxygen sensors. HI 9828-25 calibration solution is used for both pH and conductivity.

• Fill the calibration beaker 2/3 full with HI 9828-25 calibration solution.

• Slowly place the sensors into the solution and

dislodge bubbles that may adhere to the sensors.

• Screw the calibration beaker completely on the

probe body. Some solution may overflow.

• Wait a few minutes for the system to stabilize.

• From the “Calibration” menu select “Quick

calibration”.

• A three item calibration menu will appear (pH,

Conductivity and Dissolved oxygen) and “pH” will start to blink along with the “Not ready” message.

• When the pH signal is stable, the “Ready”

message appears. Press <Confirm> to store the calibration data.

• The “Storing” message will appear as the

calibration proceeds to the next sensor. A checkmark will appear in the box next to “pH” to indicate a successful calibration.

NoteNote

Note To bypass any of the calibrations press

NoteNote

<Skip> to move to the next sensor in the quick calibration menu. If the pH sensor is not installed the message “pH sensor not installed! Skip to conductivity calibration” will appear.

• Following the pH calibration, “Conductivity” will start to blink along with the

“Not ready” message.

• When the measurement is stable, “Ready” appears. Press <Confirm> to store

the calibration data and the “Storing” message will appear.

NoteNote

Note If EC calibration is not required, skip to

NoteNote

the D.O. quick calibration by pressing the <Skip> softkey.

• The message “Empty the beaker.” will appear.

• Unscrew the calibration beaker and empty the solution.

• Shake any remaining liquid off the probe and beaker. No droplets

should remain on the D.O. sensor membrane.

NoteNote

Note Do not attempt to dry wipe the D.O. sensor as damage to the mem

NoteNote

brane may occur.

• Screw the empty calibration beaker on the probe body. The beaker should not

be dry.

• Press <Accept> to close the displayed message.

• When the measurement is stable, “Ready”

appears. Press <Confirm> to store the calibration data and the “Storing” message will appear.

• Press <OK> to return to “Calibration” menu.

NoteNote

Note To quit the quick calibration procedure, press ESC at any time.

NoteNote

After every calibration the quick calibration window will show a check mark in the box next to the calibrated parameter.

7.2 pH CALIBRATION

To optimize the pH measurement follow the general guidelines mentioned in the Chapter 7 introduction.

From the “Calibration” menu select “Single param. calibration” and then “pH calibration”. The display shows two options: “Calibrate pH” and “Restore factory calib.”.

If a new pH sensor has been installed use “Restore factory calib.” before performing a user calibration as some warning messages are based on changes from previous calibrations.

If “Restore Factory Calib” is selected, all user calibration data will be deleted and the factory default calibration is restored. A user calibration should follow immediately. If “Calibrate pH” is selected, the user can perform a new calibration using up to 3 buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01 or one custom buffer).

When a 3-point calibration is performed, all old data are overwritten, while with a single or 2-point calibration the meter will also use information from the previous calibration.

7.2.1 Preparation

Pour small quantities of the selected buffer solutions into clean beakers. To minimize cross contamination, use two beakers for each buffer solution: the first one for rinsing the sensor and the second one for calibration.

7.2.2 Procedure

The measured pH value is displayed, along with the temperature and the buffer value on the second level. If necessary, press the <Cal point> softkey and use the arrow keys to select the correct buffer.

• Immerse the pH sensor in the first buffer rinse

solution and stir gently.

• Immerse the pH sensor and temperature probe

into the selected buffer and stir gently. The temperature, pH buffer value and the “Not ready” message are displayed.

• Once the reading has stabilized the countdown

timer will count down until the display shows the “Ready” message.

• Press <Confirm> to accept the calibration

point.

• After the calibration point is confirmed, to avoid cross-contamination immerse the sensors in the next calibration buffer rinse solution and stir gently.

• Press <Cal Point> to select the next buffer (if necessary), and repeat the calibration procedure outlined above with the second and third buffers.

NoteNote

Note The calibration procedure can be terminated after a single or 2 point

NoteNote

calibration by pressing <ESC>. The message “Storing” followed by “Calibration completed” will be displayed.

• Press <OK> to return to the Calibration menu.

• Press <Measure> to return to the measurement screen.

Note: If a single point calibration is conducted after restoring the factory calibra-

tion, it will offset the entire factory probe values by the same offset required to calibrate the sensor to the single buffer value.

Custom buffer calibration

The HI 9829 permits a single custom buffer to be used for pH calibration. This can be used along with standard buffers as part of a 2 or 3 point calibration or as a single point.

• To select this option first press <Cal. point> and then <Custom> while the meter is waiting for stable reading.

• A text box window will appear. Use the keypad to enter the value of the buffer at the current temperature. The valid range for custom a buffer is from 0.00 to 14.00 pH.

7.2.3 pH Calibration Error Messages

The HI 9829 displays a series of messages if an error has occurred during calibration.

If the meter does not accept a pH calibration point, a short message is displayed to indicate the possible error source. The following screens are examples:

These are the available messages:

• “Input out of scale”: the pH value is out of range. The pH sensor may require replacement.

• “Check sensor”: the electrode may be broken, very dirty or the user has attempted to calibrate the same buffer value twice. This may also occur if a new pH sensor has been installed and”restore factory calib” has not been exercised.

• “Wrong buffer”: the displayed pH reading is too far from the selected buffer value. This is often seen immediately after a buffer calibration has been completed but before the pH sensor has been moved to the next buffer. Check if the correct calibration buffer has been selected.

• “Invalid temperature”: the buffer temperature is outside the acceptable range.

• “Wrong buffer” / “Contaminated buffer” / “Check electrode”: the buffer is contaminated or the sensor is broken or very dirty.

• “Check sensor” / “Clean sensor”: the electrode is broken or very dirty.

• “Wrong” / “Clear old calibration”: erroneous slope condition. These messages appear if the slope difference between the current and previous calibration exceeds the slope window (80% to 110%). Press <Restore Factory calib.> to clear old data and continue the calibration procedure, or press ESC to quit the pH calibration mode.

7.3 ISE CALIBRATION

From the “Calibration” menu select “Single param. calibration” and then “ISE calibration”. The display shows two options: “Calibrate ISE” and “Restore factory calib”. When an ISE replaces a pH sensor or another ISE model, previous calibrations need to be cleared using the <Restore factory calib.> option first. If “Calibrate ISE” is selected, the user can perform a single (10 ppm) or 2 point calibration with standard 10 ppm and 100 ppm solutions. If “Restore Factory Calib” is selected, all user calibration data will be deleted and the default calibration is restored.

NotesNotes

Notes The ppm tag will blink when a user calibration was not performed.

NotesNotes When a 2-point calibration is performed, all of the old data is overwritten, whereas

for a single point calibration the meter will also use information from the previous calibration.

7.3.1 Preparation

Prepackaged standards are available in single use sachets. Rinse the ISE with water and shake off excess water. The procedure always uses 10 ppm first.

7.3.2 Procedure

Cut open the 10 ppm sachet and pour a small quantity of standard over the ISE tip to rinse the sensor. This should be done over a waste container. Immerse the ISE sensor and temperature probe into the standard. Position the sachet to ensure sensor membrane and ceramic junction are completely covered with solution. The current measurement or dashes, temperature, the standard value and the “Not ready” message are displayed.

• Once the ISE has stabilized the countdown timer will count down until the display shows the “Ready” message.

• Press <Confirm> to accept the calibration point.

• After the first calibration point is confirmed, remove sensor from sachet packet and shake standard off. Blot excess with a soft tissue. Cut open the 100 ppm sachet. Immerse the ISE sensor and temperature probe into the standard.

Position the sachet to ensure sensor membrane and ceramic junction are completely immersed in solution. A value close to 100 ppm and the message “Not ready...” will be displayed.

• When the reading is stable, the countdown timer will count down until the display shows the “Ready” message.

• Press <Confirm> to accept the calibration.

• After the second calibration point is confirmed the display shows the following messages: “Storing” and “Calibration completed”.

• Press <OK> to return to the Calibration menu.

• Press <Measure> to return to the measurement screen.

NoteNote

Note The ISE calibration mode can be exited at any time, by pressing the

NoteNote

ESC key.

7.4 ORP CALIBRATION

The “ORP calibration” allows the user to perform a single point custom calibration (relative mV) or to restore the factory calibration.

The Oxidation-Reduction Potential (ORP), displayed in mV, is the voltage that results from the difference in potential between the platinum ORP sensor and the silver/silver chloride reference electrode. ORP values are not temperature compensated, although ORP values can change with temperature (e.g. reference electrode potential changes, sample equilibrium changes). It is important to report ORP values together with the reference electrode used and the temperature.

The inert platinum ORP surface provides an electron exchange site with the sample (or standard) and its surface. The electron exchange is typically very fast in well-poised solutions (standards for example), but may be more lengthy in natural water samples.

Calibration is typically not required for a new ORP sensor, but the process does establish a baseline that can be used as a comparison for future validations.

Calibration is used to compensate for changes due to contamination of the platinum surface and drift in the reference electrode.

A relative mV calibration can also be made to remove the voltage attributable to the Ag/AgCl reference electrode (to display the ORP versus a SHE (standard hydrogen electrode). This is really an arithmetic correction and is correct only at the standard temperature. For example, HI 7022L reads 470 mV at 20°C versus the Ag/AgCl reference. The ORP mV versus a SHE would be 675 mV. (add 205 mV to the observed value).

7.4.1 Preparation

Appendix D – ACCESSORIES lists Hanna solutions used for ORP calibrations. The calibration should be conducted at temperatures between 20-26°C. The sensor should be clean and oil free.

7.4.2 Procedure

• From the “Calibration” menu select “Single param. calibration” and then “ORP calibration”. The display shows two options: “Custom ORP” and “Restore factory calib.”.

• For a user calibration select “Custom ORP”.

• Fill a beaker with an ORP test solution (see APPENDIX D “Accessories”).

• Using the keypad, insert the numerical ORP value and then press <Accept> to confirm.

• The stability counter will count down and the message “Ready” and <Confirm> will be

displayed.

• Press <Confirm> to accept the calibration point.

• After confirmation, the following messages are displayed: “Storing” and “Calibration completed”.

7.5 DISSOLVED OXYGEN CALIBRATION

The accuracy of dissolved oxygen measurements is directly related to membrane cleanliness and calibration technique. Oily coating and biological contaminants are the primary cause of calibration drift in dissolved oxygen sensors. Unfortunately, brushes or other cleaning objects may damage the membrane. Replacing the membrane cap and electrolyte is the best way to perform periodic maintenance.

Although it may be easier to calibrate the D.O. sensor prior to deployment, it is advised to calibrate at the site of deployment. Errors in measurement may result if altitude and barometric pressure differ between the calibration and measurement site. This is very important for autonomously logging probes.

either the % D.O. Saturation or D.O. Concentration calibration.

If the % D.O. saturation range is calibrated, the D.O. concentration range will also be calibrated, and vice versa. Dissolved oxygen concentration values are based on % D.O. saturation, temperature, salinity and atmospheric pressure. A standard solution or a reference D.O. meter may be used to compare readings during calibration. The calibration of the D.O. concentration range can only be performed at a single custom point (4 to 50 mg/L). It is recommended to calibrate the D.O. sensor close to the values that will be measured.

Choose “DO calibration” from the “Calibration” menu, select the D.O. calibration type using the arrow keys and press <Select> to confirm.

% D.O. saturation The calibration of the % D.O. saturation range

can be performed at a single or 2 standard points (0 % and 100 %), or at a single custom point (50 % to 500 %).

Procedure:

• To calibrate at 100 %, fill the calibration beaker with approximately 4 mm (5/32") of water and screw it onto the probe. The membrane should not be wet. This condition corresponds to air 100 % saturated with oxygen and water vapor.

• The reading, temperature, calibration point and the “Not ready” message are displayed.

• Once the reading has stabilized the countdown timer will count down until the display shows the “Ready” message.

• Press <Confirm> to accept the calibration point. After confirmation, put the D.O. and temperature sensors into HI 7040L zero oxygen solution and wait for stability to be reached. The stability timer will count down and <Confirm> will appear. Press <Confirm> to store the calibration.

• The following messages will appear: “Storing” and “Calibration completed”.

7.6 CONDUCTIVITY CALIBRATION

A conductivity calibration is used to adjust for variations in cell factors by using a standard solution of known conductivity. Oily coating and biological contaminants are the primary cause of calibration drift in conductivity sensors. This type of fouling changes the apparent cell geometry, resulting in a shift in cell constant. Before performing a conductivity calibration inspect the EC sensor for debris or blockages. The EC electrodes are situated inside the two small channels

found in the bottom of the conductivity sensor. Clean using the small brush from the probe maintenance kit. Flush with water. A mild detergent may be used to remove oily coatings. Always flush with clean water after cleaning.

NoteNote

Note For a correct conductivity calibration, the probe shield or the calibration

NoteNote

beaker must be used.

The conductivity calibration menu includes 3 different types of calibration: Conductivity, Absolute conductivity and Salinity.

The “Conductivity” option allows a single point calibration with a standard solution selectable by the user. This calibration is temperature compensated.

The “Absolute conductivity” option allows a single point calibration with a conductivity solution of known non-temperature compensated value at the current temperature.

The “Salinity” option allows calibration with a standard salinity solution. The 3 calibrations are related, so that each one will calibrate all 3 measurements.

7.7 TURBIDITY CALIBRATION

From the “Calibration” menu select “Single param. calibration” and then “Turbidity calibration”. The display shows two options: “Calibrate turbidity” and “Restore factory calib”.

The Hanna turbidity sensor conforms to ISO 7027 standards which specifies the angle between the emitted and detected light and the light source wavelength. For best results perform a three point calibration at 0.0, 20.0, and 200.0 FNU. Although the basis of calibration for this measurement is the standard Formazin, from a practical point of view, these standards require daily preparation. A secondary standard based upon polystyrene beads is a more practical approach. See APPENDIX D – Accessories for information regarding Hanna calibration solutions.

Note:Note:

Note: Turbidity standard formulations made with polystyrene beads are

Note:Note:

instrument specific and cannot be swapped with standards made for another turbidity sensor model.

Verify the sensor is clean before calibrating. The use of the HI 7698293 calibration beaker is required for this procedure.

APPENDIX A - PROBE MAINTENANCE

The HI 7698292 probe maintenance kit includes HI 7042S (electrolyte solution for D.O. sensor), spare membranes with o-rings for D.O. sensor, a small brush for cleaning EC , o-rings for sensor connectors and a syringe with grease to lubricate these o-rings.

General Maintenance

• Inspect all sensor connectors for corrosion and replace sensors if necessary.

• Inspect sensor o-rings for nicks or other damage and replace sensor if necessary. Lubricate only with grease from kit.

Use only the supplied grease as some lubricants can cause the o-rings to expand or affect the turbidity calibration standards.

• After prolonged storage or cleaning, calibration of the sensors is required.

• After use rinse the probe with tap water and dry it. The pH electrode bulb must

be kept moist. Dry the D.O., EC and EC/Turbidity sensors. Dry ISE sensors and return to their storage caps if they will not be used for a period of time.

• Check GLP data under “Status” to ensure the sensor is still functioning

properly.

pH and pH/ORP Sensor Maintenance

• Remove the sensor protective cap. Do not be alarmed if any salt deposits are

present. This is normal with pH/ORP electrodes and they will disappear when rinsed with water.

••

• Shake down the sensor as you would do with a clinical thermometer to eliminate

••

any air bubbles inside the glass bulb.

••

• If the bulb and/or junction are dry, soak the electrode in HI 70300 storage

••

solution for at least one hour.

••

• To ensure a quick response time, the glass bulb and the junction should be kept

••

moist and not allowed to dry. Store the sensor with a few drops of HI 70300 storage solution or pH 4.01 buffer in the protective cap. Tap water may also be used for a very short period (few days).

Never use distilled or deionized water to store pH sensors

••

• Inspect the sensor for scratches or cracks. If any are present, replace the sensor.

••

• Cleaning procedure: clean the sensor frequently by soaking it for 1 minute in

HI 70670 or HI 70671 cleaning solution. After cleaning soak the sensor in HI 70300 storage solution before taking measurements.

D.O. Sensor Maintenance

I•Before sevicing, rinse the probe with tap water.

• If a more thorough cleaning is required, clean the probe body and sensor with

the supplied brush or a non-abrasive detergent.

If any deposit scales the

sensor, gently brush the sensor surface with the supplied brush, while paying attention to not damage the plastic body. Do not use the brush on the membrane.

For a top performance probe, it is recommended to replace the membrane every 2 months and the electrolyte monthly. While the cap is off, inspect the sensor internal electrodes.

• If the zinc anode (Concentric metal electode than surrounds internal stem)

appears coated with a white substance or is dull, clean by gently wiping with the plastic scouring pad that is included in the maintenance kit.

To replace the membrane cap or electrolyte proceed as follows:

• Unscrew the membrane by turning it counterclockwise.

• Rinse a spare membrane with some electrolyte while shaking it gently. Refill

with clean electrolyte.

• Gently tap the cap over a surface to ensure that no air bubbles remain

trapped. Avoid touching the membrane.

• With the sensor facing down, completely screw the cap clockwise. Some

electrolyte will overflow.

EC Sensor Maintenance

• After every series of measurements, rinse the probe with tap water.

• If a more thorough cleaning is required, clean the sensor with the supplied

brush or a non-abrasive detergent. Ensure that the two cylindrical holes in the sensor are free of foreign material.

EC/Turbidity Sensor Maintenance

• After every series of measurements, rinse the probe with tap water.

• If a more thorough cleaning of the sensor is required, clean the EC cylindrical

holes in the sensor with the supplied brush or a non-abrasive detergent. Ensure that the two cylindrical holes are free of foreign material.

• Gently remove any material that is attached to the face of the turbidity sensor

taking care to not scratch the optical windows. Use a soft cloth and nonabrasive detergent.

• If there are cracks or scratches on the optical windows, the EC/turbidity sensor

must be replaced.

ISE Sensor Maintenance

• After measurements inspect o-ring, connector and body. Rinse ISE sensor with

tap water to remove films or other coatings.

••

• Shake down the sensor as you would do with a clinical thermometer to eliminate

••

any air bubbles.

• Soak the electrode in its corresponding 10 ppm calibration solution for at least

1/2 hour prior to calibration. Store dry in protective cap when not in use.

• For long-term storage rinse the electrodes with water. Shake off the excess

water and replace the storage cap to prevent evaporation of the reference electrolyte. Do not use hard pH caps used for other product lines. Do not store in water or pH storage solution.

• For chloride sensors (HI 7609829-11), if the sensor pellet appears tarnished,

use a polishing strip to remove the oxidized surface. Cut off approximately a 1 inch piece of the strip. Wet the frosted side with water and place against damaged surface. Place your thumb against the shiny backing and slowly rotate back and forth while applying gentle pressure.If dark deposits appear on the frosted surface, move the paper slightly. Continue polishing until you are satisfied with the surface. Rinse sensor with water. Do not use hard pH caps used for other product lines. Do not store in water or pH storage solution

General Guidelines for fixed installation:

General Guidelines for fixed installationGeneral Guidelines for fixed installation

• Select a water-sampling site that will allow collection of representative water samples.

• Position the probe so the sensor surfaces face toward the flow. This will minimize air bubble or fluid cavitation. Limit flow rate to moderate

• Mount Probe 0 to 45° angle from vertical to avoid sensors (pH, pH/ORP, ISE) from becoming electrically discontinuous due to internal electrolytes flowing away from their internal cells.

• Install meter or probe where they will be accessible for maintenance as required.

• Regularly visit water sampling sites to: check for damage to sensors, the installation mountings, and the probe/meter battery power.

• Remove aquatic weed growth that may be interfering with water sample collection.

• Set up devices and programs for water monitoring and sampling.

• If the probe is suspended from a pier or bridge ensure that it is protected from debris by positioning behind a support and anchoring the cable /probe to a pipe.

• Have access to spare sensors and proper range standard solutions or buffers.

• Strictly follow the established SOP’s.

• Download data to a laptop computer or meter on site.

• Protect probe and sensors from excessive sunlight.

• Flow cell installation; Avoid trapped air. Maintain constant flow rate.

The Hanna HI 76X0929 has been designed for a variety of water quality measurements both in situ or in active deployments in urban or natural waters. The HI 9829 systems may be used for discrete spot sampling with a meter and the meter’s log on demand function, unattended with continuous monitoring and logging from the meter, or unattended using a logging probe. These data are then downloaded to a meter or PC and can be plotted with logging software to obtain the graphical log needed for interpretation of the essential physical property of the aqueous body of water. In all of these deployment situations data quality is dependent upon the site location, service intervals, amount of coatings, sedimentation and vegetation, and the actual installation. The probe may be installed in a horizontal bank (fixed installation) or a vertical suspension. The maximum depth rating of 20 m (65’) for the probe should be adhered to. (Note: actual sensor specifications may be less). The location must be accessible for the duration of the measurement (consider seasonal flooding, freezing and other acts of nature) when selecting a site. Many conditions may affect the quality of measurements. Select an installation site that is representative of the water body being monitored. Avoid areas without adequate water circulation. To protect equipment it is best to avoid exposure to wind, foam, turbulence, air temperature gradients/sun, extended periods of high flow, extended periods of high sediment and floating debris. The standard operating procedures (SOP) for the data gathering must be upheld. This typically includes pre and post deployment checks of the sensors to validate data gathered between calibrations, upholding service intervals, and following any other sitespecific procedures. Grab samples for laboratory analysis or spot sampling with another probe are addition ways to validate the measurements taken by unattended continuous logging probes.

The probe is suitable for installation in confined locations such as air vaults, river intakes, vertical wells, tanks, etc.. The streamline diameter of the probe permits insertion into 2" pipelines. Unlike probes that require a cable support for active deployments the probe can be manually lowered and raised by the cable due to it’s superior strength member.

It is suitable for installation in open moving waters; rivers, streams, ditches (farmland drainage), conveyance canals, etc.. In these cases protecting the probe from debris is important. If the probe is suspended from a pier or bridge position it behind a support and anchor the cable/probe to a pipe.

It is suitable for deployment in open waters; monitoring lakes, ponds, wetland basin, infiltration basins, bays. Schedule regular service to remove aquatic weed

The probe is suitable for measurements in a flow cell. Pumping water to a flowthrough monitoring station has obvious pros and cons. Typically a shelter is required to secure a pump, and flow chamber. A power requirement, shelter, pump maintenance and higher installation cost need to be considered. Freeze protection, security, and convenience of calibration and possibility of adding multiple measurement points and antifouling preconditioning systems are advantages to this type of installation.

APPENDIX C - ISE INFORMATION

This Appendix describes additional information about the ISE sensors used on the HI76x9829 Probe.

HI 7609829-10: Ammonium selective electrode (ISE) is a combination liquid membrane sensor used for the detection of free ammonium-nitrogen in freshwater samples. The sensor utilizes a polymeric membrane made with ammonium ionophore in a PVC head and silver/silver chloride double junction gel filled reference electrode. The outer body of the sensor is the thermoplastic PEI. This sensor is used in place of the pH.

The measurement of ammonium-nitrogen, NH measurement of surface water contaminants such as tracing the source of agricultural operations runoff or studying nutrient levels in natural waters. HI 7609829-10 is an ion selective sensor that responds to the free Ammonium ion. Ammonium ion is the ionized portion of the total ammonia concentration and the amount present depends on pH. When the pH of the sample is below 8 pH, the primary form of ammonia is ammonium ion. See figure below. The relationship is more complicated with increasing salinity but the two forms together equal total ammonia.

The ammonium sensor will last longer in colder clean waters than in severely contaminated water or warmer waters. This is because the active chemicals responsible for the ammonium ion sensitivity are leached out of the membrane with continued exposure. As the sensor ages there will be a decreased sensitivity until the sensor will no longer calibrate or operate properly. The lifetime of the sensor depends greatly on deployment conditions.

Although HI 7609829-10 is selective toward ammonium ions, it also responds to other ions which can interfere with the measurement. The ratio of interfering ion to ammonium ion must be less than the ratio indicated below:

Sodium: 90 Potassium: 0.75 Calcium: 125 Magnesium: 4000

Exposure to these interferences does not cause permanent damage to the sensor. Note that the potassium ion interference is the strongest, and its concentration must be less than the ammonium concentration to have no effect.

The sensor utilizes a polymeric membrane made with nitrate ionophore in a PVC head and a silver/silver chloride double junction gel filled reference electrode. The outer body of the sensor is the thermoplastic PEI. This sensor is used in place of the pH sensor in the probe.

The measurement of Nitrate-Nitrogen, NO

-N is a useful tool in the measurement

of surface water contaminants such as tracing the source of agricultural operations runoff or studying nutrient levels in natural waters. HI 7609829-12 is an ion selective sensor that responds to the free nitrate ion.

Although all forms of nitrogen including nitrogen gas (N2) are interconvertible within the nitrogen cycle as a function of oxidation state, the nitrate sensor only detects the ionized form.

HI 7609829-12 is specified for 0.62 to 200 ppm (mg/L) NO to 2.74 - 885.6 ppm (mg/L) NO

). Based on the corresponding molecular

weights of nitrogen and nitrate, the relationship is: NO

) x 0.2258.

The sensor responds in a Nernstian manner (like a pH sensor) and produces a voltage that the meter converts to a concentration value.

The calibration solutions and displayed measurements are as ppm Nitratenitrogen. Due to the space restriction of the display the unit of measurement

will be displayed as “ppmNi”

The nitrate sensor will last longer in colder clean waters than in severely contaminated water or warmer waters. This is because the active chemicals responsible for the nitrate ion sensitivity are leached out of the membrane with continued exposure. As the sensor ages there will be a decreased sensitivity until the sensor will no longer calibrate or operate properly. The lifetime of the sensor depends greatly on deployment conditions.

Although HI 7609829-12 is selective toward nitrate ions, it also responds to other ions which can interfere with the measurement. Organic solvents and cationic detergents must be absent. Chloride has the largest interference for natural waters. The ratio of interfering ion to nitrate ion must be less than the ratio indicated below:

Fluoride: 300 Nitrite: 4 Chloride:100 Iodide: 0.01 Carbonate: 4 Perchlorate: 0.0045
