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.
