HYDROLAB pH and ORP Sensor for HL Series Sonde, Standard Reference

Product #: HLPHORPSREF
Brand: HYDROLAB
Unit Price Contact Hach

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.  HYDROLAB's ORP sensor uses a platinum band that donates or accepts electrons to monitor chemical reactions, quantify ion activity, or determine the oxidizing or reducing properties of a solution.
