Overview
Overview
The HYDROLAB pH sensor uses a glass bulb measuring electrode with integrated refillable reference electrode, combined into one 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.
