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.
