Refillable pH and ORP Probes
Demanding applications can leach the electrolyte from the pH sensor causing measurement inconsistency and eventual failure. Hamilton refillable pH sensors solve this problem by allowing the user to replenish the electrolyte.

WHAT MAKES REFILLABLE SENSORS DIFFERENT?
-
Replenish The electrolyte
Processes like pure water, leach electrolyte from the sensor. Sensors like the IonoTrode allow manual refilling without removing the sensor, saving downtime and replacement costs.
-
Up the pressure, up the life
By using external pressure, the ChemoTrode can deliver consistent electrolyte flow. Process chemicals that would normally poison or clog the sensor are displaced. The design solves critical applications in the chemical, petrochemical, and oil / gas industry.
-
Great for continuous applications
Refillable sensors work well in continuous measurement applications such as flowing pipelines or flowcells. The sensor can be isolated through armature for service or simply serviced online.

What is a refillable sensor and why would I choose it?
Refillable sensors have a port that allows manual replenishment of the reference electrolyte. Processes like pure water leach out out the electrolyte so the Ionotrode is a good choice. Other products like the ChemoTrode allow the for externally pressurized electrolyte so the process liquid cannot easily contaminate the sensor. -
How do I clean an ORP sensor?
The platinum band around the tip of the ORP sensor can oxidize over time. Light scrubbing with a mild abrasive such as toothpaste will remove the oxidization. Rinse with potable water and store in storage solution prior to usage -
What is the difference between ORP and Redox?
They are the same. Redox is a shortened word for “Reduction Potential”. ORP is shortened for “Oxidation Reduction Potential”. The sensor and measurement is the same.
