1.3 GENERAL DESCRIPTION

HI9828 is a multiparameter system that monitors up to 13 different water qual-

ity parameters (6 measured, 7 calculated). The microprocessor based multisensor probe allows to measure all the param-

eters necessary to evaluate the water quality, as dissolved oxygen saturation percentage, conductivity, seawater specific gravity and other parameters that ensure life in water as pH and temperature. The same probe can be used with different meters without needing any recalibration.

HI9828 is also provided with a built-in 12 channel GPS receiver and antenna, that guarantee 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 HI929828 software. GPS information can also be viewed using a GPS mapping software such as Google™ Maps. Clicking on visited locations using a mapping software such as Google™ Maps displays measurement information. For measuring points within a 10 meter range or where GPS signal is not available, HI9828’s Fast Tracker™ is invaluable for associating measurements with their locations. HANNA’s exclusive Fast Tracker™—T.I.S. (Tag ID System) monitors and records data using iButton®s that can be installed at any number of sampling sites. HI9828 features a graphic, backlit display that automatically sizes the digits to fit the screen and allows full configuration of each parameter measured along with on-screen graphing capability. Designed for outdoor environments, waterproof, resistant and easy to use, HI9828 is the ideal solution for field measurements of lakes, rivers and sea. The meter meets IP67 standards (30 minutes immersion under 1 m of water); the multi sensor probe can be left underwater (IP68 standard). The setting menu can be protected by password to avoid not authorized modifications and the help function is always available to explain the selected function, operation or message.

1.5 PROBE DESCRIPTION & INSTALLATION

HI9828HI9828

HI9828 is supplied with a multisensor probe for dissolved oxygen, temperature,

HI9828HI9828 conductivity, pH and redox measurements.

1.5.1 Sensor Description

The galvanic DO sensor allows to obtain stable readings in a few seconds. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. Oxygen that passes through the membrane causes a current flow, from which the oxygen concentration is determined. Before installing the probe, it is necessary to activate the DO sensor; see paragraph 1.5.3 for details.

The conductivity sensor uses the 4-ring technology that allows stable and linear readings without any interference in the whole range.

The pH/ORP sensor features a glass membrane for pH readings and a Pt sensor for redox measurements. To avoid clogging problems and ensure a fast response, the pH bulb must be kept moist at any time. Store the electrode with a few drops of

HI70300HI70300

HI70300 storage solution in the pro-

HI70300HI70300

tective cap.

The EC sensor also works as matching pin and must be always mounted to have correct pH readings.

For correct redox measurements, the surface of the electrode must be clean and smooth, and a pretreatment procedure should be performed to ensure quick response.

Since the Pt/PtO system depends on the pH, the pretreatment of the electrode may be determined by the pH and the redox potential values of the solution to be measured.

As a general rule, if the ORP (mV) reading corresponding to the solution pH value is higher than the values in the table below, an oxidizing pretreatment is necessary; otherwise perform a reducing pretreatment.

Temperature sensor

The DO probe is shipped dry. To hydrate the sensor and prepare it for use, proceed as follows:

• 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 the membrane.

• Rinse the supplied membrane with some electrolyte solution while shaking it gently. Refill with clean electrolyte. Gently tap the membrane over a surface to ensure that no air bubbles remain trapped. To avoid damaging the membrane, do not touch it with your fingers.

• With the sensor facing down screw the cap clockwise to the end of the threads. Some electrolyte will overflow.

1.5.4 Installation

The multisensor probe can support 3 different sensors: DO, EC, pH or pH/ORP. To make easier the installation, the sensors are color coded.

For a correct installation, proceed as follow:

• Grease the O-ring gaskets.

• Insert the sensor while paying attention to the correct alignment with the corresponding colored connector. Fix the sensor by screwing the locking nut with the supplied tool.

• When all sensors are mounted, screw the protection sleeve for taking measurements or the transparent beaker for calibrating.

• With the meter off, connect the probe to the DIN socket on the bottom of the instrument by aligning the pins and pushing in the plug. Tighten the nut to ensure good connection.

1.7 POWER CONSUMPTION

For firmware versions before 2.0, the meter never features the GPS unit and the battery life does not depend on logging interval or logging state:

• supplied rechargeable batteries (full charge): approximately 70 hours of continuous use, without backlight

• alkaline batteries: approx. 150 hours of continuous use, without backlight

For firmware version 2.0 and subsequents, see below table: to find out the battery life, make a crossing between GPS use and logging interval.

All values refer to meter working without LCD backlight, and using the supplied rechargeable batteries (completely charged).

If using the device in normal measuring mode with the backlight always on and no GPS, the battery life will be approximately 80 hours with rechargeable batteries and 160 hours with alkaline batteries.

4.2 pH CALIBRATION

It is recommended to calibrate the meter often for pH readings, especially if high accuracy is required.

When the pH calibration is selected, the display shows two options: “Calibrate pH” and “Clear old calibration”.

If “Calibrate pH” is selected, the user can perform a new calibration at 1, 2 or 3 points with standard buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01), or a single calibration with custom buffer.

If “Clear old calibration” is selected, all calibration data will be deleted and the default data restored.

NotesNotes

Notes Old calibration data have to be deleted every time the pH sensor is

NotesNotes

replaced and after performing a cleaning procedure.

When a 3-point calibration is performed, all the old data are overwritten, while with a 1 or 2-point procedure the meter will use for the missing points the data previously stored with the last 3-point calibration.

4.2.1 Preparation

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

4.2.2 Procedure

The current measured value is shown on the main part of the display, while the buffer value appears on the secondary level.

If necessary, press the <Buffer> softkey to change the buffer value or insert a custom buffer.

1, 2 or 3-point calibration

• Immerse the probe into the selected buffer and stir gently. The current pH value, the buffer value and “Not ready” are displayed.

• When the reading becomes stable and close to the selected buffer value, the display shows the “Ready” message.

• Press <Confirm> to accept the calibration point or <Buffer> to select another buffer using the arrow keys.

• After the first calibration point is confirmed, immerse the probe in the second buffer solution and stir gently.

• When the reading is stable and close to the selected buffer, the display shows the “Ready” message.

• Press <Confirm> to accept the point or <Buffer> to change the buffer.

• After the second calibration point is confirmed, immerse the probe in the third buffer solution, stir gently and wait for stable reading.

• When the calibration is completed, the display shows the following messages: “Storing data on probe, please wait...”, “Updating GLP data, please wait ...” and “Calibration completed”.

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

• To return to the main menu, press ESC repeatedly.

NoteNote

Note The pH calibration mode can be quitted at any time, by pressing the

NoteNote

ESC key.

Custom buffer calibration HI9828 also allows a single point procedure to

calibrate with a custom buffer value.

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

• A text box window will appear for inserting the desired custom value. The valid range for custom buffer is from 0.00 to 14.00 pH.

4.2.3 Error List

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

These are the available messages:

• “Input out of scale”: the pH value is out of scale.

• “Wrong buffer”: the pH reading is too far from the selected buffer value. Check

if the correct calibration buffer has been selected.

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

• “Wrong buffer” / “Contaminated buffer” / “Check electrode”: the buffer is

contaminated or the electrode is broken or very dirty.

• “Wrong electrode” / “Check electrode” / “Clean electrode”: 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.

4.3 DISSOLVED OXYGEN CALIBRATION

If the DO % saturation range is calibrated, the DO concentration range will also be calibrated, and vice versa.

The DO % saturation value is referred to the DO concentration in air (100%). For this reason it is recommended to calibrate the probe near the area where the measurements will be taken.

Also note that the DO concentration values are based on DO % saturation, temperature, salinity and atmospheric pressure. It is recommended to use a standard solution or a reference DO meter to compare readings during calibration.

The calibration of the DO % saturation range can be performed at 1 or 2 standard points (0% and 100%), or at a single custom point (50 to 500%).

The calibration of the DO concentration range can be performed at a single custom point (4 to 50 mg/L).

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

DO % saturation The default first calibration point is 100 %.

• Fill the calibration beaker with approximately 4 mm (5/32”) of distilled water

and screw it onto the probe.

• The message “Not ready...” is displayed until a

stable reading is reached.

• To change the calibration value, press the <Cal.

point> softkey and select the desired point.

• To insert a different calibration value, press

<Cal. point> and then <Custom>. Insert the desired value using the keyboard.

• When the reading is stable, the “Ready” mes-

sage is displayed. Press <Confirm> to store the calibration point.

• After the first calibration point is confirmed, put the probe in a zero oxygen

standard solution and wait for stable reading.

• Press <Confirm> to store the calibration point.

• The following messages will appear: “Storing data on probe, please wait...”,

“Updating GLP data, please wait ...” and “Calibration completed”.

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

• To return to the main menu, press ESC repeatedly.

NoteNote

Note The user can perform a single point calibration with standard values.

NoteNote

To abort the procedure, press ESC after the first point is accepted. If the DO input is not within the acceptable range, the message “Invalid

input” is displayed.

DO concentration To calibrate the DO concentration range, a solution with known DO concentra-

tion value is needed.

• From the “DO calibration” menu, select the

“DO concentration” option, insert the known value and press <OK>.

• When the reading is stable, press <Confirm>

to accept the value.

• When the messages “Storing data on probe, please wait...”, “Updating GLP

data, please wait ...” and “Calibration completed” appear, the calibration is completed. To return to the “Calibration” menu, press <OK>.

• To return to the main menu, press ESC repeatedly.

4.4 CONDUCTIVITY CALIBRATION

For a correct conductivity calibration, the probe sleeve must be inserted.

The conductivity calibration menu includes 3 different types of calibration: Conductivity, Actual 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 “Actual conductivity” option allows a single point calibration with a custom conductivity solution of known actual value (not temperature compensated).

The “Salinity” option allows calibration with a standard salinity solution.

The 3 options are correlated, so that each of the procedures will calibrate all the 3 ranges.

APPENDIX A - PROBE MAINTENANCE

HI9828HI9828

HI9828 is supplied complete with a probe maintenance kit that includes

HI9828HI9828 HI7042SHI7042S

HI7042S (electrolyte solution for DO sensor), 5 spare membranes with O-

HI7042SHI7042S rings for DO sensor, a small brush for cleaning EC and DO sensors, 5 O-rings for sensor connectors and a syringe with grease to lubricate these O-rings.

General Maintenance

After use rinse the probe with tap water and dry it. The pH electrode bulb must be kept moist. Dry the DO and EC sensors.

Maintenance of DO Sensor

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 membrane over a surface to ensure that no air bubbles remain trapped.

• 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.

Maintenance of pH Probe

• Remove the electrode protective cap. Do not be alarmed if any salt deposits are present. This is normal with pH electrodes and they will disappear when rinsed with water.

••

•Shake down the electrode 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

•• solution for at least one hour.

••

•To minimize clogging and ensure a quick response time, the glass bulb and the

•• junction should be kept always moist and not allowed to dry.

••

•Store the electrode with a few drops of

•• cap. Tap water may also be used for a very short period (couple of days).
