Overview

This sensor is used for conductivity of water measuring. The measuring principle is to place two electrodes with a fixed area and distance in the liquid to be measured, apply a constant voltage at both ends of the electrode plate (generally a sine wave voltage to avoid polarization effect), under the action of the electric field, ions in solution will move in a certain direction. Measure the current passing between the plates, and calculate to obtain the conductivity of the liquid to be measured.
