The Global Water’s Conductivity Controllers are high performance digital indicating, dual set point, ON/OFF controllers for conductivity, that use a temperature compensated conductivity probe. The Conductivity Controllers have a K=1.0 cell constant conductivity probe with a front panel cell adjustment potentiometer. The conductivity controller features an analog voltage output of 1 mV/LSD for recorders, printers, computer interfacing peripherals, ect. The conductivity controller’s display is a large 0.56” high efficiency bright red LED. The overall conductivity indication and control range for the model 3101 is 0 to 200 mS/cm, multiple ranges can be selected via internal DIP switches. The conductivity controllers are packaged inside of a 1/8 DIN front panel mount enclosure. Conductivity controller probe connectors are spade lug type. All conductivity controllers are heat cycled 100 hours prior to shipment.
