Description

The CDCN-961 conductance, resistance or total dissolved solids (TDS) controller is designed for in-line monitoring of process solutions and water applications.

The CDCN-961 has a simple menu for easy set-up. Available relays can be configured for control, alarm or as a calibration reminder. The transmitter output can also be set from the keypad, eliminating the need for potentiometer or dip-switch settings. The calibration function automatically recognises the buffer solution resulting in a simple and straight forward system calibration.
