WEL pH/ORP Sensors
WDP and WPH Series Controllers are a perfect match with Walchem's WEL pH/ORP electrodes - offering an extremely reliable differential measurement technique immune to any possible ground loop problems. Together they provide a true NEMA 4X system with no BNC connectors exposed to wet or corrosive conditions. Walchem's pH/ORP controllers and sensors are engineered to give you the most reliable measurement and control available. |
WDS pH/ORP Sensors
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. |
