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 per-
centage, conductivity, seawater specific gravity and other parameters that en-
sure 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 in-
formation that can be viewed immediately on the display.
GPS information can be transferred to a PC using HANNA’s HI929828 soft-
ware. 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 avail-
able, HI9828’s Fast Tracker™ is invaluable for associating measurements with
their locations. HANNA’s exclusive Fast Tracker™—T.I.S. (Tag ID System) moni-
tors 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 modifi-
cations and the help function is always available to explain the selected function,
operation or message.

1.5 PROBE DESCRIPTION & INSTALLATION
HI9828HI9828
HI9828HI9828
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 de-
termined. Before installing the probe, it is necessary to acti-
vate the DO sensor; see paragraph 1.5.3 for details.
The conductivity sensor uses the 4-ring technology that al-
lows stable and linear readings without any interference in
the whole range.
The pH/ORP sensor features a glass membrane for pH read-
ings 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
HI70300HI70300
HI70300 storage solution in the pro-
tective cap.
The EC sensor also works as matching pin
and must be always mounted to have cor-
rect pH readings.
For correct redox measurements, the surface of the elec-
trode must be clean and smooth, and a pretreatment pro-
cedure should be performed to ensure quick response.

12
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.

1.5.3 DO Sensor Activation
The DO probe is shipped dry. To hydrate the sensor and prepare it for use, pro-
ceed 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 corre-
sponding 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 mea-
surements 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 push-
ing 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 batter-
ies and 160 hours with alkaline batteries.

Chapter 3 - SETUP MODE
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.
3.1 MEASUREMENT SETUP
• Switch the meter on by pressing on/off.
After the initialization has been completed, the
meter enters the measurement mode. The active
softkeys are <Log> and <Menu>.
•Press <Menu>, select “Measurement Setup” us-
ing the arrow keys, then press <OK>.
•The display shows the complete list of measur-
able parameters.
•To select a parameter, scroll with the arrow keys.
Each parameter can be enabled or disabled. A checked box or the measure unit
means that the parameter is enabled. Press the right softkey to enable or disable
the parameter.
Some parameters also allow to select measure unit and resolution by pressing
the <Unit> or <Resolution> softkey respectively.
NoteNote
NoteNote
Note If the password protection is enabled, the meter will ask to insert the
password prior to change the first parameter.
Temperature
The user can select the measure unit: °C, °F or K.

22
pH, pH-mV, ORP, DO % Saturation, Salinity
These parameters can only be enabled or disabled; measure unit and resolution
are fixed.
DO concentration
The user can select ppm or mg/L measure unit.
Conductivity and Actual Conductivity
The user can select among the following options:
Auto (autoranging for all µS/cm and mS/cm
ranges), 1 µS/cm, 0.001 mS/cm, 0.01 mS/cm,
0.1 mS/cm, 1 mS/cm, Auto mS (autoranging for
mS/cm ranges).
NoteNote
NoteNote
Note Actual conductivity is the conductivity value measured with no tempera-
ture compensation.
Resistivity
The user can select the measure unit among
Ω·cm, kΩ·cm and MΩ·cm.
TDS
The user can select among the following options:
Auto (autoranging for all ppm [mg/L] and ppt
[g/L] ranges), 1 ppm (mg/L), 0.001 ppt (g/L),
0.01 ppt (g/L), 0.1 ppt (g/L), 1 ppt (g/L), Auto ppt
(g/L) (autoranging for ppt [g/L] ranges).
NoteNote
NoteNote
Note For setting ppm or mg/L, see paragraph 3.2 “System Setup”.
Seawater specific gravity
This parameter is widely used for seawater analysis, it is similar to a density mea-
surement and gives indication about the salt content. It depends on water pres-
sure, temperature and salinity.
In the seawater specific gravity menu the user can select the reference tempera-
ture: σt, σ0and σ15 (i.e. current temperature, 0°C and 15°C).
Atmospheric pressure
The user can select among the following mea-
sure units: atm, kPA, mmHg, inHg, mbar, psi.
