GENERAL DESCRIPTION Hanna Instruments HI 9032 is a microprocessor-based, bench-top, conductivity meter designed for the laboratory stringent demands, with the ability to perform five types of measurements: · Conductivity (4 different ranges: 0.0 to 399.9 µS/cm, 399 to 3999 µS/cm, 3.99 to 39.99 mS/cm, 39.9 to 99.9 mS/cm) · Fertilizer Concentration (F1 or F2 in the range 0.00 to 39.9 g/l) · NaCl of sea water saturation (range 0.0 to 130.0%) · Temperature (range 0.0 to 50.0°C) · Total Dissolved Solids (3 different ranges: 0.0 to 199.9 ppm, 0 to 1999 ppm, 0.00 to 19.99 g/l). 3 ins rum n sCompany ISO 9000 Certified since 1992 e 2 HI 9032 automatically recognizes buffers @ 84 µS/cm, 1413 µS/cm, 12.88 mS/cm, 80.0 mS/cm. Commands are easily accessible through the user-friendly keyboard: Through the COND key the meter is set in the conductivity range, TDS key selects Total Dissolved Solids measurements, NaCl key sets the range to NaCl measurement, and the FERT key selects 1st or 2nd fertilizer measurements. Temperature compensation can be either automatic or manual. It can be selected through the key ATC / MTC respectively. A temperature coefficient factor (for conductivity measurements) can be also selected through the %TC key (from 0.0 to 3.0%). The TDS factor (for TDS measurements) can be selected through the FTR key (from 0.01 to 0.99). The unit includes memory storages for all calibration data even after the unit is shut off. HI 9032 is equipped with two liquid crystal displays: · A large one in two sections (primary and secondary LCD) indicates conductivity, TDS, NaCl, Fertilizer and temperature coefficient %; · A smaller one indicates temperature. The meter also incorporates a standard R232C output to allow serial communication with a host computer; a series of programs can be selected for the setting of the R232C baud rate.

Temperature display This LCD displays the temperature measured by the HI7669/2W probe or the value that was manually set through the keyboard. Temperature can be selected between the Celsius and the Fahrenheit scale by pressing the °C or the °F key respectively. If the probe is not connected when the meter is turned on, the "25°C" (or "77°F") symbol with a blinking decimal point will default. 5 4 If the temperature probe is disconnected during operation, the decimal point will start blinking. It will blink also if the temperature range is exceeded. This LCD also displays the program # during programming. 3. Calibration Procedure Briefly describes calibration procedure 4.

Power connection Plug the 12VDC adapter (HI710005 or HI710006) into the DC socket (#6). Plug the adapter into the mains. Note: The instrument uses the following configuration. 1. DIN female socket for the conductivity probe (HI7686) 2. Temperature probe socket for use with the HI7669/2W 3. Reset button 4. Potentiometer for conductivity calibration (0.0µS) 5. RS 232C socket for serial communication. 6. DC Power Socket (for HI710005 or HI710006). + - It is recommendable to use Hanna HI710005 or HI710006 voltage adapters (supplied with the meters) that use the proper polarity configuration. HI 9032 can also be used with other adapters. In this case, remember to check the correct polarity of your adapter before connecting it to the meter. Note: · Make sure the main line is protected by a fuse. · If you need to unplug the instrument, press the OFF key before disconnecting the meter from the mains. Probes connection Connect the supplied conductivity probe HI7686 securely to the DIN socket provided (#1) by aligning the pins with the socket, pushing the plug in and tightening the threaded ring. For temperature measurements and automatic temperature compensation connect the temperature probe HI7669/2W to the °C socket (#2). RESET button The RESET button (#3) is used when the instrument displays erroneous messages due to strong electrical interference or when the instrument's power supply was disconnected before the meter was switched off. Press the 8 9 SPECIFICATIONS OPERATIONAL GUIDE Make sure that the instrument has been calibrated before taking measurements (see calibration procedures on page 21 for conductivity, page 31 for NaCl and 35 for fertilizer). Connect the conductivity probe to the meter securely by aligning the pins with the socket on the back of the meter, pushing the plug in and tightening the threaded ring. Connect the temperature probe to the back of the meter for automatic temperature compensation or for temperature measurements. If possible, to minimize any EMC interferences, use plastic beakers for the solutions. MEASURE COND. FERTILIZER NaCl TDS TEMP. RESOLUTION COND. FERTILIZER NaCl TDS TEMP. ACCURACY (@20°C/ 68°F) TEMP.
