Dear Customer,
Thank  you for choosing a Hanna product. This manual will
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using
the meter. If you need additional technical information, do

These instruments are in compliance with the   directives.

HI 983321-0  and HI 983321-1 are conductivity  indicators
and controllers with a relay output designed for simplicity of
use in a wide range of  applications.
The models are panel mounted with membrane keypads on
the front panel and an easy-to-read LCD display.
All the meters automatically compensate for the temperature
variation. The probe is easy to clean and requires little
maintenance.
Measurements are highly accurate and the meters can be
calibrated at one point.
Power supply, wiring and selection are made via the plug-
in terminal blocks on the rear panel.
LED indicators on the front panel identify whether the
controller is in set or measurement mode, and if alarm is
active.

Recommendations for Users
Before using these products, make sure that they are entirely suitable for

the environment in which they are used. Operation of these instruments in

residential areas could cause unacceptable interferences to radio and TV

equipment. The metal band at the end of the probe is sensitive to electro-

static discharges. Avoid touching this metal band at all times. During operation,

ESD wrist straps should be worn to avoid possible damage to the probe by

electrostatic discharges. Any variation introduced by the user to the sup-

plied equipment may degrade the instrument’s EMC performance.
To avoid electrical shock, do not use these instruments when voltage at the

measurement surface exceeds 24 VAC or 60 VDC. Use plastic beakers to

minimize any EMC interferences.
To avoid damage or burns, do not perform any measurement in microwave

ovens.
