Four-Electrode Sensors

546 Four-Electrode Inline/Submersible/High Pressure "Hot Tap" Sensors

The 546 Four-Electrode Conductivity sensor can be used with all the same hardware as the 546 pH / ORP sensors. Ideal for conductivity measurement in clean chemical applications the 546 sensor provides high accuracy in a much smaller package than competing toroidal sensor technology.
