1.3 GENERAL DESCRIPTION

HI 9828 is a multiparameter system that benefits from years of experience of Hanna Instruments as a manufacturer of analytical instruments. Waterproof, resistant and easy to use, it is the ideal solution for field measurements of lakes, rivers and sea. Thanks to the microprocessor based multisensor probe, it is possible to measure all the parameters 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. It is also possible to use the same probe with different meters without the need to recalibrate the system.

Up to 12 parameters can be enabled and seen on the large graphic display with backlight. All readings can be memorized and associated to a precise sampling area thanks to the i-Button© system and the remarks that the operator can insert before or during measurements. The same data can be plotted on the meter and also downloaded to a PC by means of USB connector and HI92000 Windows® compatible application for successive elaborations.

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.

The main features of HI9828 series include:

•Measurement of dissolved oxygen, pH, ORP, conductivity and related parameters, temperature, atmospheric pressure and seawater specific gravity

•Field replaceable sensor modules for DO, EC and pH/ORP

•5 interface languages: English, Spanish, French, Portuguese, Italian

•Graphical display with backlight

•GLP features

•i-Button© system to remark the sampling area

•Up to 60,000 samples stored in 100 different lots

•Four C size Ni-MH rechargeable batteries

•Batteries recharged from mains power supply and from cigarette lighter

•Password protection

1.4 POWER SUPPLY

HI9828 runs with 4 rechargeable C size, Ni-MH batteries.

On the display the battery symbol visualizes the remaining battery charge. When this symbol starts blinking, it is necessary to recharge or replace them with new ones. When the batteries are completely rundown the meter automatically shuts off to avoid wrong readings.

1.4.1 Batteries installation

Battery replacement must only take place in a nonhazardous area.

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

Move the switch down toward the probe connector if using rechargeable batteries. Move the switch up for alkaline batteries.

Alkaline batteries can explode or leak when attempting to recharge them with the switch set to down position.

1.4.2 Recharging batteries

HI9828 is supplied with two cables for recharging batteries: HI710045 and

HI710046.

Mains power supply

In order to recharge batteries from the mains power supply, use HI710045 combined with the 12 Vdc adapter.

•With the meter OFF, disconnect the probe.

•Connect HI710045 to the meter and to the power adapter; connect the adapter to the mains power supply.

•The message “Battery charging in progress” appears and then the battery symbol.

•A complete batteries recharging will last about 14 hours.

9

Cigarette lighter supply

To recharge HI9828 from a vehicle cigarette lighter supply, use HI710046.

•Simply connect the cable to the meter and to the car’s cigarette lighter.

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

•A complete batteries recharging will last about 14 hours.

NOTE Batteries can also be recharged with the meter ON; if the auto-off feature is enabled, the meter turns off automatically after the set time.

1.5 PROBE DESCRIPTION & INSTALLATION

HI9828 is supplied with the multisensor probe for dissolved oxygen, temperature, conductivity, pH and redox measurements.

1.5.1 Sensors description

The galvanic D.O. sensor allows to have 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 D.O. 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 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 responses.

10

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

For reducing pretreatment: immerse the electrode for a few minutes in HI 7091L. For oxidizing pretreatment: immerse the electrode for a few minutes in HI 7092L.

1.5.3 D.O. sensor activation

The D.O. probe is shipped dry. To hydrate the probe 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 electrolyte 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 electrodes, DO, EC, pH/ORP. To make easier the installation, the 3 sensors have 3 proper color codes.

For correct sensor 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 calibration.

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

the bottom of the meter by aligning the pins and pushing in the plug. Tighten the nut to ensure a good connection.
