Summary
Combination pH Sensor Installation
Answer
If your sensor does not have a temperature compensation element, you can use cable (Product #) 1W1125. If your sensor does include a temperature compensation element, you can use cables (Product #) 1W1125 and 1W0980. Both are sold by the foot. The sensor signal cable is a RG-58 coaxial cable, which uses the center conductor for the active signal, and the braided shield as the reference. The temperature compensation cable is a standard 22 AWG 2-wire/shielded cable.
