1.1 PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any damage, notify your Dealer or the nearest HANNA Customer Service Center immediately.

Note Save all packing materials until you are sure that the instrument 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,

6

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.

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.

Chapter 4 - PROBE INSTALLATION

HI 7609829 and HI 7629829 multisensor probes are used for the measurements of pH, ORP, conductivity, turbidity, dissolved oxygen, chloride, nitratenitrogen, ammonium-nitrogen and temperature. Each probe can utilize 3 sensors. A description of each sensor follows.

4.1 SENSOR DESCRIPTIONS

HI 7609829-0 Combination pH sensor features a glass pH sensitive bulb and a silver/silver chloride double junction reference with gelled electrolyte.

HI 7609829-1 Combination pH/ORP sensor features a glass sensitive bulb for pH readings, a platinum sensor for redox measurements and a silver/silver chloride double junction reference with gelled electrolyte.

Note See section 4.2.1 for pH preparation. See section 4.2.2 for ORP activation.

HI 7609829-2 Galvanic dissolved oxygen (D.O.) sensor. The thin gas permeable membrane isolates the

sensor elements from the testing solution but allows oxygen to pass through. The oxygen that passes through the membrane is reduced at the cathode and causes a current, from which the oxygen concentration is determined. The D.O. sensor conforms to Standard Methods 4500-AG, EPA 360.1.

Note The D.O. sensor needs to be activated before installation. See section 4.2.3 for details.

HI 7609829-3 4-electrode conductivity sensor. The sensor is immune to polarization or surface coatings.

The HI 7609829-4 Combination EC/Turbidity sensor. It includes a 4-electrode conductivity sensor and a turbidity sensor that conforms to ISO 7027 standards in a single sensor body. The turbidity sensor uses an optical technique to measure suspended particles in water.

19

HI 7609829-10: Ammonium selective electrode (ISE) is a combination liquid membrane sensor used for the detec-

tion of free ammonium-nitrogen in freshwater samples. The sensor utilizes a polymeric membrane made with ammo-

nium ionophore in a PVC head and silver/silver chloride double junction gel filled reference electrode. This sensor is used in place of the pH sensor in the probe.

HI 7609829-11: The Chloride ISE is a combination solid state sensor used for the detection of free chloride ions in freshwater samples. The sensor utilizes a silver chloride pellet housed in a PEI head and a silver/silver chloride double junction gel filled reference electrode. This sensor is used in place of the pH sensor in the probe.

HI 7609829-12: The Nitrate ISE is a combination liquid membrane sensor used for the detection of nitrate nitrogen in freshwater samples. The sensor utilizes a polymeric membrane made with nitrate ionophore in a PVC head and a silver/silver chloride double junction gel filled reference electrode.

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.

pH	m V	pH	m V	pH	m V	pH	m V	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 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.

21

•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 HI 9829-10, 10 ppm NH4+-N standard for at least a 1/2 hour.

4.2.6 Chloride 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 HI 9829-12, 10 ppm Cl- standard for at least a 1/2 hour.

4.2.7 Nitrate 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 HI 9829-14, 10 ppm NO3--N standard for at least a 1/2 hour.

22

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.

Note The EC/Turbidity sensor with 9 pin connector does not have a color-coded cap. It is always installed into the socket with three blue triangles.

23

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.

Chapter 5 - INITIALIZATION AND MEASUREMENT

5.1 BATTERY INSTALLATION

HI 9829 is supplied with 4 rechargeable, size C NiMH (Nickel-metal hydride) batteries.

The battery symbol on the LCD indicates the remaining battery charge. The meter has a low battery warning, and when the symbol starts blinking, batteries should be charged or replaced with new ones. When the batteries are discharged the meter will automatically shut off to avoid erroneous readings.

5.1.1 Meter Battery Installation

Replace batteries in nonhazardous areas only.

Remove the 4 screws on the rear of the instrument and insert the batteries observing polarity.

If you wish to replace the supplied rechargeable batteries with

nonrechargeble alkaline batteries, move the switch in the bat-

tery compartment upward. A warning message is

displayed if you

connect the charging cable to a meter with alkaline batteries.

Nonrechargeable alkaline batteries can explode or leak if you try to charge them. Verify that the switch is in the up position when using

alkaline batteries to prevent recharging.

Note: Do not mix old and new alkaline batteries.
