Industrial process conductivity/temperature controllers CDTX-111 and CDTX-112 are panel instruments for in-process monitoring of conductivity. Range switch over and cell constant checks can both be freely set and adjusted during operation. Unique signal collection and processing technology, and a special thick film circuit are employed to ensure accurate measurements and stable operation. Other features include linearized data, automatic temperature compensation, and maintenance-free cells. The control functions trigger relays based on conductivity setpoints. The CDTX-111 and CDTX-112 are ideal auxiliary instruments for many types of water testing applications.

The manual calls for 1 calibration level, however is it possible to calibrate multiple levels using different known standard solutions? I am having an issue with full range 0-2000us accuracy.
About your CDTX-111 conductivity monitor, we need it to monitor the water resistivity in real tome. I have a quetion to ask: Terminal Pin 12 & Pin 13 behind it is connected to the temperature sensor, is this sensor necessary in our application?
