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
ON
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
OFF
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.
Rinse the probe thoroughly in distilled water or if possible with a small amount of the calibration solution. This is to minimize con­tamination of the calibration solution and se­cure higher accuracy.
When possible, use plastic beakers to mini­mize any EMC interferences.

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.

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
3
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.
