Walchem® WEL Series Electrodes with In-line Mounting

Cost-effective differential pH and ORP electrodes for industrial applications. Modular in design with a rugged CPVC housing that contains the electronics. pH and ORP cartridges can easily be connected or replaced without tools. Cartridge has a unique threaded interlock connection and a double O-ring seal to ensure a watertight fit and secure seating at all times. Titanium solution ground rod integrals to the housing to enable the differential measuring technique, resulting in prolonged electrode life and reliable measurement, resistance to stray voltages and currents, or ground loop problems. Electrode is powered by the controller it is connected to allowing the signal to always be preamplified without batteries that can die.
