pH Sensor

pH Sensor for Hydrolab mulitparameter sondes

The Hydrolab pH sensor uses a glass bulb measuring electrode and refillable reference electrode.

There are two versions available:

pH with standard reference uses a separate measuring electrode and reference electrode, each in their own sonde port
pH with integrated reference combines the measuring electrode and reference 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
The choice of standard or integrated refillable reference allows flexibility in sonde configuration
The pH measuring electrode hosts the optional ORP sensor
