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?
What is the expected lifetime of my pH sensor?Expected pH sensor lifetime is dependent on the application. Exposure to strong chemicals, elevated temperature, fluctuating pressure, and solid build-up can all impact the sensor life. As the sensor ages, a sluggish response may become more apparent, and will require more frequent calibrations to compensate for this change. The overall health of the Arc pH sensors can be seen using the quality indicator in ArcAir software. Click to learn more about sensor lifespan and expiration in the Knowledgebase article.
What solution should I store my pH or ORP probe in?Hamilton recommends storing pH and ORP probes wet in either Hamilton Storage Solution (Ref 238931) or in 3M KCl solution. Click to see the pH/ ORP Sensor Storage and Regeneration Knowledgebase for more information.
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
