HYDROLAB pH Sensor for HL Series Sonde with Standard Reference

Overview The HYDROLAB pH sensor uses a glass bulb measuring electrode and refillable reference electrode, each in their own sonde port. A user-rebuildable reference electrode extends the life of the pH sensor while minimizing costs because the measuring electrode does not necessarily need replacement when the reference electrode is depleted.
