• ATC
· · Automatic temperature compensation
HI23 is a wall mounted, microprocessor
conductivity controller that provides very
accurate measurements due to the four-
ring EC probe and Automatic Temperature
Compensation (ATC) feature.
Users can choose among models featuring
ON/OFF or PID control, analog input and
output, double set point. The relay contacts
can drive external devices such as pumps or
electrovalves.
The input signal can come from a probe or a
4-20 mA transmitter. Models with the RS485
output option are also available. This option
allows the user to insert the controller into a
2-wire RS485 network.
