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

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