GENERAL DESCRIPTION

Hanna Instruments HI9032 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).

HI9032 automatically recognizes buffers @84µS/cm, 1413µS/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.

TAKING TEMPERATURE MEASUREMENTS

Taking a temperature measurement is very easy. Connect the temperature probe

to the instrument and turn the meter on by pressing the ON key.

Dip the liquid/general purpose temperature probe HI7669/2W into the sample and allow the reading on the TEMP. display to stabilize (1 or 2 minutes).

Note: If the temperature probe is not con-

nected when the meter is turned on, the instrument will automatically default a temperature of 25.0°C (or 77.0°F) on the TEMP. LCD with a blinking decimal point.

AFTER MEASUREMENTS

When all measurements are

completed the meter should be turned off by pressing the OFF key and the probe cleaned.

See page 59 for the probe cleaning and maintenance procedure.

Note: The probe body and sleeve are very

susceptible to damage due to temperatures exceeding 50°C (122°F). If the probe is exposed to high temperature, the bond between the rings and the probe body may become impaired and the probe will not function properly, in which case it has to be replaced.

CONDUCTIVITY CALIBRATION

INITIAL PREPARATION

There is a choice of 4 memorized buffers. Choose the solution whose conductivity value is closer to the value of the sample measured:

• 84 µS/cm @ 25°C using HI7033 (or HI8033) conductivity solution

• 1413 µS/cm @25°C using HI7031 (or HI8031) conductivity solution

• 12.88 mS/cm @ 25°C using HI7030 (or HI8030) conductivity solution

• 80 mS/cm @ 25°C using HI7034 (or HI8034) conductivity solution.

The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion.

The conductivity invariably increases with increasing temperature.

It is affected by the type and number of ions in the solution and by the viscosity of the solution itself.

Acids, alkalis and concentrated salt solutions have lower values, typically 1.5%/°C.

Since a small difference in temperature causes a large change in conductivity readings the readings are usually normalized at 25°C.

HI 9032 automatically compensates for temperature differences when used with the temperature probe provided.

• Condition the sample and probes at 25°C and write down the conductivity reading "C25".

• Condition the sample and probes to a temperature t°C which is approximately 5°C to 10°C different from 25°C and note the conductivity reading "Ct".

• The temperature coefficient ß of the solution is calculated with the formula:

(Ct - C25)

TDS

The TSD value in aqueous solutions is directly proportional to the conductivity of a solution.

The ratio between the two measures depends on the solution and usually it is set to a factor of 0.5 (CaCo

). This means that

each µS/cm is converted in 0.5 mg/l or

0.5 ppm. With HI 9032 the TDS factor can be set to

the most appropriate value depending on the solution to be measured.

For accurate TDS measurements with HI9032 make sure the meter has been calibrated in conductivity and the temperature coefficient is properly set.

INTERFACE WITH PC

Data transmission from the instrument to the PC is now much easier with the new HI 92000 Windows® compatible application software offered by Hanna Instruments.

User friendly, HI 92000 offers a variety of features and has an on line help feature to support you throughout all situations.

HI 92000 allows you to use the powerful means of the most diffused spread sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply run your favorite spread sheet and open the file downloaded by HI 92000. It is then possible to make any elaboration available with your software (e.g. graphics, statistical analysis).

To install HI 92000 you need a 3.5" drive and few minutes to follow the instructions conveniently printed on the disk's label.

IContact your Hanna Dealer to request a copy.

To connect your HI 9032 to the PC use HI 920010, available through your Hanna Dealer. Make sure that your meter is switched off and plug the connectors, one into the meter RS232C connector, the other into the serial port of your PC.

Note: Cables different from the HI 920010

may use a different configuration. In such case any communication between the meter and the PC is not possible.

If you are not using Hanna Instruments HI 92000 application software, please find here below some additional information to help your connection to the PC.

SETTING THE BAUD RATE AND THE COMMAND PREFIX

See program # 1.

CHANGING THE COMMAND PREFIX

Sometimes it is necessary to change the command prefix. If your computer already uses the DLE character for control purposes, sending it to the conductivity meter can be difficult or cause your computer to behave erratically.

To avoid this problem, you can change the command prefix to almost every ASCII character (0 - 127 decimal).

To change the command prefix, refer to PGM 2 operation.

The carriage return is the only character that cannot be used as a command prefix. Good choices for command prefix are ESC (ASCII code 27), SO (ASCII code 15), or any printing character you will not use for other purposes; e.g. the C symbol (ASCII code 64).

SENDING COMMANDS FROM PC

With terminal programs such as, for example, Telix®, Windows Terminal®, HyperTerminal®, it is possible to remotely control your HI 9032. Use HI 920010 cable to connect the meter to the PC, start the terminal program and set the communication options as follows: 8, N, 1, no flow control.

Command Types To send a command to the pH meter the

scheme is: <DLE> <

command>

<CR>

This line makes the computer send a Data Link Escape character, the command expressed as a number or a 3-character sequence) and a CR character.

Note: Windows Terminal® and all the other

terminal programs that support the ANSI escape sequence, represent the DLE character by the string '^P' and the CR character by the string '^M'. E.g. the line '^PPHR^M' sets the range to pH.
