NoteNote

functions correctly. Any damaged or defective items must be returned in their original packing material with the supplied accessories.

1.2 MODEL IDENTIFICATION

Meter: There are two models for the meter:

HI 9829: Portable multiparameter meter HI 98290: Portable multiparameter meter with GPS

Probe: There are two base models of multiparameter probes:

HI 7609829: Standard multiparameter probe HI 7629829: Multiparameter probe with autonomous logging

capability

All meters and probes are fully compatible with each other, and all available measurement sensors can be used on both probe models.

Different combinations of meters, probes, sensors and accessories can be ordered either in predefined configurations or individually. See Appendix D for ordering configurations.

For example, ordering codes of probes follow: HI 7609829/X is a HI 7609829 probe with X meter cable for pH/pH+ORP/

ISE, D.O., EC, temperature sensors with a short probe shield HI 7619829/X is a HI 7609829 probe with X meter cable for pH/pH+ORP/

ISE, D.O., EC+turbidity, temperature sensors with a long probe shield HI 7629829/X is a HI 7629829 logging probe with X meter cable for pH/

pH+ORP/ISE, D.O., EC, temperature sensors with a short probe shield HI 7639829/X is a HI 7629829 logging probe with X meter cable for pH/

pH+ORP/ISE, D.O., EC+turbidity, temperature sensors with a long probe shield

1.3 GENERAL DESCRIPTION HI 9829 is a portable logging multiparameter system that monitors up to 14

different water quality parameters (7 measured, 7 calculated). The microprocessor-based intelligent multisensor probe allows measurement of

many water quality parameters such as pH, ORP, turbidity, dissolved oxygen,

conductivity, chloride, nitrate, ammonium and temperature with data logging. The system is easy to setup and easy to use.

The HI 98290 with GPS option has a built-in 12 channel GPS receiver and antenna that guarantees 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 HI 929829 software. GPS information can also be viewed using a GPS mapping software such as Google™ Maps. Clicking on visited locations using a mapping software displays the measurement information.

All HI 9829 are equipped with Fast Tracker™ an invaluable tool for associating measurements with their locations. HANNA’s exclusive Fast Tracker™—T.I.S. (Tag ID System) uses

iButton®s that can be installed at any number of sampling sites.

The HI 9829 features a graphic, backlit display that automatically sizes the digits to fit the screen with on-screen graphing capability. Each parameter is fully configurable.

HI 9829 was designed to withstand harsh environments and is the ideal solution for field measurements of lakes, rivers and sea. The meter meets IP67 standards (30 minute immersion at a depth of 1 m) and the multisensor probe meets IP68 standards (continuous immersion in water). Settings and logged data can be protected with a passcode to avoid unauthorized modifications and context-sensitive help is always available.

Main features of the HI 9829 system:

• Rugged meter and probe

• Easy to use

• Measure up to 16 parameters and display of up to 12 parameters

• Tracking of measurement locations with GPS (optional)

• Waterproof protection (IP67 for the meter and IP68 for the probe)

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

• Graphic LCD with backlight

• Built-in barometer for D.O. concentration compensation

METER BATTERY LIFE

The power consumption of the HI 9829 multiparameter system is dependent on three things:

1. The measurement system configuration (probe type, sensor configuration)

2. The meter configuration (logging interval, GPS and backlight use)

3. The battery type (alkaline or rechargeable). Note: Alkaline batteries have two times the expected life.

The following table estimates the meter’s battery life connected to a HI 76X9829 probe with backlight off. The logging interval only affects meter

battery life when GPS Powersave mode is used (units with GPS). (Note: GPS and backlighting use consume the most power). The table variables are GPS, battery selection and parameter selection. Note: When a HI 7629829 logging probe is connected to a meter, it uses the meter’s power.

4.2 SENSOR PREPARATION / ACTIVATION

4.2.1 pH Preparation

Remove the shipping cap from the pH sensor. If the shipping cap does not contain any liquid, pour HI 70300 into shipping cap, place it back on the sensor and soak for at least 1/2 hour before use. If HI 70300 is not available, pH 4.01 buffer may be substituted.

4.2.2 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.

For reducing pretreatment: immerse the electrode for at least five minutes in HI 7091.

For oxidizing pretreatment: immerse the electrode for at least five minutes in HI 7092.

4.2.3 D.O. Sensor Activation

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

• Remove the black & red plastic shipping cap and discard.

• Insert the supplied O-ring in to the membrane cap.

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

Gently tap the black 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.

4.2.4 EC and EC/Turbidity Sensor Preparation

The EC and EC/Turbidity sensors do 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.

4.2.5 Ammonium Sensor Preparation

Remove the shipping cap and inspect sensor. Verify no air pockets have developed near the ceramic junction during shipping. Hold the sensor at the connector and shake it down (like a mercury thermometer). Condition the sensor by soaking it in a small amount of

4.3 SENSOR INSTALLATION

The HI 76x9829 can support 3 different sensors: Connector 1: pH, pH/ORP or ISE (Ammonium, Chloride, Nitrate), Connector 2: D.O., Connector 3: EC or EC/Turbidity.

To make installation easier, the sensors have color-coded caps and the sockets are identified with colored triangles.

NoteNote

Note The EC/Turbidity sensor with 9 pin connector does not have a

NoteNote

color-coded cap. It is always installed into the socket with three blue triangles.

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 mainte

nance 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. Tighten the knurled, threaded shell.

• 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.
