Walchem’s WDS Series differential pH and ORP sensors are designed for industrial applications to be long-lasting and reliable.
The differential measurement technique uses two electrodes, one for the process measurement and the other for the reference measurement. Each electrode is measured differentially with respect to a third metal electrode. The reference electrode is constructed from pH glass and is embedded in pH 7 buffer within the sensor behind a porous, replaceable salt bridge.
