FAQ

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.

FAQ

Does Hamilton make pH sensors for high pressure applications?

Yes, our Polilyte Plus sensors are rated to 10 Bar (145 PSIG) from 0 to 130C. The Polilyte Plus XP version of these sensors is rated up to 16 Bar (232 PSIG) from 0 to 130C and can handle up to 50 Bar (724 PSIG) at lower temperatures. Learn more at the link below.

FAQ

What is a polymer-filled sensor and why would I choose it?

Polymer-filled sensors use solid (or nearly solid) electrolyte. This design keeps electrolyte from flowing out of the sensor and process liquid from poisoning or clogging the sensor. Polymer filled sensors are a great choice for industrial applications with strong chemicals, particulates and elevated pressures.
