HI7698194‑0 Combination pH sensor features a glass pH sensitive

bulb and a silver/silver chloride double junction reference with gelled electrolyte.

HI7698194‑1 Combination pH/ORP sensor features a glass sensitive

bulb for pH readings, a platinum sensor for redox measurements and a silver/silver chloride double junction reference with gelled electrolyte.

Note: See page 18 for pH preparation. See page 18 for ORP activation.

HI7698194‑2 Galvanic dissolved oxygen (D.O.) sensor. The thin gas

permeable membrane isolates the sensor elements from the testing solution but allows oxygen to pass through. The oxygen that passes through the membrane is reduced at the cathode and causes a current, from which the oxygen concentration is determined. The D.O. sensor conforms to Standard Methods 4500‑AG, EPA 360.1.

Note: The D.O. sensor needs to be activated before installation. See page 18 for details.

HI7698194‑3 four ring‑electrode conductivity (EC/TDS/Resistivity/Sa‑

linity) sensor. The sensor is immune to polarization or surface coatings.

Page 18

SENSOR PREPARATION / ACTIVATION

pH Preparation

Remove the shipping cap from the pH sensor. If the shipping cap does not contain any liquid, pour

HI70300 into shipping cap, place it back on the sensor and soak for at least 1/2 hour before use. If HI70300 is not available, pH 4.01 buffer may be substituted.

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.

pH mV pH mV pH mV pH mV pH mV

0 990 1 920 2 860 3 800 4 740 5 680 6 640 7 580 8 520 9 460

10 400 11 340 12 280 13 220 14 160

For reducing pretreatment: immerse the electrode for at least five minutes in HI7091. For oxidizing pretreatment: immerse the electrode for at least five minutes in HI7092.

D.O. Sensor Activation

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

• Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown away.

• Insert the supplied O‑Ring in to the membrane cap.

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

Gently tap the 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.

Page 19

EC Sensor Preparation

The EC sensor does 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.

SENSOR INSTALLATION

The HI7698194 can support three different sensors: Connector 1: pH, pH/ORP Connector 2: D.O. Connector 3: EC.

To make installation easier, the sensors have color‑coded caps and the sockets are identified with colored triangles, corresponding to the colors of the sensors (pH ‑ red; EC ‑ blue; D.O. ‑ white).

Page 20

The HI7698195 support two different sensors:

Connector 1: pH, pH/ORP Connector 2: EC

The HI7698196 support two different sensors:

Connector 1: pH, pH/ORP Connector 2: D.O.

SENSOR INSTALLATION

Page 21

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 maintenance 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. Secure the probe by attaching the carabinier of the probe to the meter piston.

• 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.

The temperature coefficient Beta (ß) is defined by the following equation (using 25 °C as an example): EC25=ECx /(1+ß(Tx‑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.

TDS Factor (HI98194, HI98195 only)

TDS stands for total dissolved solids, and it is a calculated value based on the conductivity of the solution (TDS = factor x EC25). The TDS conversion factor can be set from 0.00 to 1.00. A typical TDS factor for strong ionic solutions is 0.50, while for weak ionic solutions (e.g. fertilizers) is 0.70. Press Modify to enter the value, press Accept to confirm. The default

value is 0.50.

Salinity (HI98196 only)

This value is used to calculate the D.O. concentration where the EC sensor is not available for the meter. To set the value, press Modify and enter the desired value between 00.00 to 70.00 PSU. Press Accept to save the modification.

Averaging

Averaging is a software filter to minimize sensor noise and provide more stable readings. Averaging is particularly useful to get a rep‑ resentative reading of the “average” value from flowing water. Averaging will affect all measurements.

Page 29

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.

Note: Each reading takes 1 second, so when logging the first sample will be delayed by a few seconds if averaging is used.

HI9819X’s calibration routines are accessed by highlighting

“Calibration” and pressing Select from the main menu. Calibration is the process that standardizes the electrical signal 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.

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

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. 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 dif‑ ferent 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.

Chapter 7 - CALIBRATION MODE

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 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, if exists.

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.

pH CALIBRATION

Page 32

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 / keys to select the correct buffer.

• Immerse the sensors 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.

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

Custom buffer calibration

Page 33

pH Calibration Error Messages

The HI9819X 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.

• “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 the Clear softkey to cancel the old data and continue the calibration procedure, or press ESC to quit the pH calibration mode.

pH CALIBRATION

Page 34

RELATIVE mV 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, HI7022 reads 470 mV at 25 °C versus the Ag/AgCl reference. The ORP mV versus a SHE would be 675 mV. (add 205 mV to the observed value).

Preparation

APPENDIX C – “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.

Page 35

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”.

• Press OK to return to the Calibration menu.

• Press Measure to return to the measurement screen.

• To restore the factory calibration data, select the corresponding option in the “ORP calibration” menu and then press Select.

DISSOLVED OXYGEN CALIBRATION (HI98194, HI98196 only)

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.

Note: Perform 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 pres‑ sure. A standard solution or a reference D.O. meter may be used to compare readings during calibration.

RELATIVE mV CALIBRATION

D.O. CALIBRATION (HI98194, HI98196 only)

Page 36

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 / 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 approxi‑ mately 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

HI7040 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”.

Page 38

CONDUCTIVITY CALIBRATION (HI98194, HI98195 only)

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.

Note: For a correct conductivity calibration, the probe shield or the calibration 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 calibra‑ tion 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.

Note: To improve accuracy, choose a calibration standard near the sample conductivity.

Choose “Conductivity calibration” from the “Calibration” menu. Select the calibration type using the / keys and press Select to confirm.

The HI7698292 probe maintenance kit includes HI7042S (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. and EC sensors.

• 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 HI70300 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 HI70300 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.

APPENDIX A - PROBE MAINTENANCE

Page 58

• Cleaning procedure: clean the sensor frequently by soaking it for 1 minute in HI70670 or

HI70671 cleaning solution. After cleaning soak the sensor in HI70300 storage solution before

taking measurements.

D.O. Sensor Maintenance (HI98194, HI98196 only)

For a top performance probe, it is recommended to replace the membrane every 2 months and the electrolyte monthly. 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.

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.

EC Sensor Maintenance (HI98195, HI98196 only)

• 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.

APPENDIX A - PROBE MAINTENANCE

Page 59

APPENDIX B - PROBE DEPLOYMENT

The Hanna HI769819X have been designed for a variety of water quality measurements both in situ or in active deployments in urban or natural waters.

The HI9819X systems may be used for discrete spot sampling with log on demand function or, continuous monitoring and logging. These data can be downloaded to a PC and 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 site‑specific procedures. Grab samples for laboratory analysis or spot sampling with another probe are addition ways to validate the measurements taken by unattended continuous logs.

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 growth that may be interfering with representative water samples.

Page 60

The probe is suitable for measurements in a flow cell. Pumping water to a flow‑through 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 mea‑ surement points and antifouling preconditioning systems are advantages to this type of installation.

General 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) from becoming electrically discontinuous due to internal electrolytes flowing away from their internal cells.

• Install meter and 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 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.

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