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.

Main features of the HI 9828 system:

• Simultaneously displaying of up to 12 parameters

• Tracking of measurement locations with GPS (optional)

• IP67 waterproof protection for meter and IP68 for probe

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

• Graphic LCD with backlight

• Built-in barometer for DO compensation

• Quick Calibration feature

1.4 POWER SUPPLY

Cigarette lighter supply

HI9828 is supplied with 4 rechargeable C size, Ni-MH batteries.
The battery symbol on the LCD shows the remaining battery charge. When the

symbol starts blinking, batteries should be charged or replaced with new ones.
When the batteries are completely rundown the meter automatically shuts off to
avoid erroneous readings.

1.4.1 Battery Installation

Battery replacement must only take place in a
nonhazardous area.

Remove the 4 screws on the rear of the instru­ment and insert the batteries while paying at­tention to the correct polarity.

If using rechargeable batteries, move the switch
down toward the probe connector. Move the
switch upward for not rechargeable alkaline bat­teries.

Not rechargeable batteries can explode or leak if attempting
to charge them with the switch set to down position.

1.4.2 Charging Batteries

HI9828 is supplied with two cables for charging batteries: HI710045 and
HI710046.

Mains power supply
In order to charge batteries from the mains, use the HI710045 cable and the

supplied 12 Vdc adapter.

• With the meter OFF, disconnect the probe.

• Connect the HI710045 to meter connector and power adapter, then con-

nect the adapter to the mains.

• The message “Battery charging in progress”
will appear on the LCD, followed by the bat­tery symbol.

• A complete battery charging will last about
14 hours.

To charge batteries from a vehicle cigarette lighter supply, use HI710046 cable.

• Simply connect the cable to the meter and to the cigarette lighter plug.

• The message “Battery charging in progress” will appear on the display, fol­lowed by the battery symbol.

• A complete battery charging will last about 14 hours.

Note Batteries can also be charged with the meter ON; if the auto-off fea-

ture is enabled, the meter turns off automatically after the set time.

1.5 PROBE DESCRIPTION & INSTALLATION

HI9828 is supplied with a multisensor probe for dissolved oxygen, temperature,
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 HI70300 storage solution in the pro­tective 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.

10

11

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.

pH mV 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

1.5.3 DO Sensor Activation

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.

For reducing pretreatment: immerse the electrode for a few minutes in HI 7091.

For oxidizing pretreatment: immerse the electrode for a few minutes in HI 7092.

coordinates (depending on model and if the GPS feature is enabled). See Chap­ter 3 for details.

• Press <Log> to store the readings or <Menu> to enter in the main menu. See
Chapter 5 for details.

Note If no probe is detected, the message “Probe disconnected!” appears. In

this case only the <Menu> softkey is available and only a few func­tions are active (i.e. those that not require readings).

Up to 12 measurements can be enabled at the same time, and based
on number of enabled parameters, the display automatically changes
its resolution and sizes the digits to fit the screen.

A few parameters have to be set before taking any measurements. In the main
menu two setup options are available: “Measurement” and “System”.

Measurement setup allows to set the displayed readings and their units, while
the system setup is used to set all system parameters, as the interface language,
date and time, LCD contrast, acoustic signals, etc.

Chapter 4 - CALIBRATION MODE

HI9828 allows to perform six different types of calibration, one for each pa­rameter, and a quick single-point procedure for some of them.

Calibration data are stored in the non volatile memory of the probe, so that the
same probe can be used with different meters without needing new calibration.

• To perform a calibration procedure, select the
“Calibration” option from the main menu and
press <OK>.

Note If password protection is enabled and

the latest performed action was a not
password protected feature, the meter
will ask to insert the password.

• Select the desired calibration type with the arrow keys and then press <OK>.

Available options are:
Quick calibration (single point procedure to calibrate DO saturation, pH and

conductivity ranges), pH, DO, conductivity, atmospheric pressure, ORP and tem­perature.

4.1 QUICK CALIBRATION

(*) only for model featuring GPS system.

28

The quick calibration feature allows a fast and easy field calibration of the
multisensor probe, using only one solution (HI9828-25).

• Fill the calibration beaker with the HI9828-25 calibration solution.

• Screw the calibration beaker on the probe body. Some solution will overflow.

• Wait a few minutes for the system to stabilize.

• Select the “Quick calibration” option from the
“Calibration” menu and press <OK>.

• A 3-item (pH, Conductivity and Dissolved oxy­gen) screen appears. “pH” starts blinking and
the “Not ready” message is shown.

29

• When the measure is stable, “Ready” is shown.
Press <Confirm> to store calibration data.

• The messages “Storing data on probe, please
wait...” and “Updating GLP data, please wait
...” appear.

Note If pH calibration is not required, the meter allows to skip to the EC

quick calibration, by pressing the <Skip> softkey.
If the pH sensor is missing the message “pH sensor not installed! Skip

to conductivity calibration” appears.

• After the pH calibration is completed, the
“Conductivity” option will start blinking.

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

• The messages “Storing data on probe, please
wait...” and “Updating GLP data, please wait
...” appear.

Note If EC calibration is not required, skip to the DO quick calibration, by

pressing the <Skip> softkey.

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.

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

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.

• The message “Empty the beaker. Shake the
probe and put it in the beaker again” appears.

• Unscrew the calibration beaker and remove
the solution.

• To dry the probe shake it as you would do with a clinical thermometer. Pay
attention that no drops remain on the DO sensor.

Note Do not use paper to dry the probe, to not damaging the sensor.

• Screw back the calibration beaker on the probe body.

• Wait for stable reading and then press <OK> to close the displayed message.

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

• The messages “Storing data on probe, please wait...” and “Updating GLP data,
please wait...” appear.

• The 3-item calibration screen appears again
and the checkboxes corresponding to the cali­brated parameters will be marked.

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

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

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.

31

• 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.

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

ESC key.

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:

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.

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” mes­sage 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.

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

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.

APPENDIX A - PROBE MAINTENANCE

HI9828 is supplied complete with a probe maintenance kit that includes
HI7042S (electrolyte solution for DO sensor), 5 spare membranes with O-

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.

58

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 HI70300 storage
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 HI70300 storage solution in the protective
cap. Tap water may also be used for a very short period (couple of days).

NEVER USE DISTILLED OR DEIONIZED WATER TO STORE THE
pH ELECTRODE.

59

• Inspect the electrode for scratches or cracks. If any is present, replace the

electrode.

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

HI70670 or HI70671 cleaning solution. After cleaning soak the electrode in
HI70300 storage solution before taking measurements.

Maintenance of EC Probe

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

• If a more thorough cleaning is required, clean the probe with the supplied
brush or a nonabrasive detergent.

Notes

• After a cleaning procedure, always recalibrate the system.

• Grease the O-rings before installing back the sensors.
