Industrial Grade Digital Controllers Wall Mounted with Four-ring Potentiometric Probe
- Works with four-ring potentiometric probe
- Automatic EC calibration
- Automatic Temperature Compensation
HI 23 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.
Each HI 23 model is provided with dual set point and is supplied complete with instructions.
