Viscous liquid gel-filled sensors provide a suitable upgrade for the entry level sensors used in many industries. The added viscosity of the electrolyte helps slow the ingress of process contaminants from poisoning the reference element.
WHAT MAKES VISCOUS LIQUID-FILLED SENSORS DIFFERENT?
Hamilton has been working with this viscous liquid-filled electrolyte technology for over 20 years.
Most Hamilton viscous liquid filled sensors have additional agency approvals and certifications for appropriate usage in a wide variety of industries.

What is viscous electrolyte?
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
