Model 546 Four-Electrode Conductivity Sensor

Ideal for conductivity measurement in clean chemical applications the 546 sensor provides high accuracy in a much smaller package than competing toroidal sensor technology.

As the name suggests, four electrode sensors add an additional pair of electrodes to the two electrode sensor design. This second pair of electrodes provides sensor diagnostics which can then be used to compensate the measurement if scale or particulate build-up occur on electrodes. Four electrode conductivity sensors can withstand coating and scale which might otherwise foul a traditional two electrode sensor.
