HYDROLAB pH Sensor for HL Series Sonde, Standard Reference

# de producto: HLPHSREF
Marca: HYDROLAB
Ships within 3-5 weeks

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
