Polymer-Filled pH and ORP Sensors
Polymer-filled pH sensors provide good longevity and stability in many applications. The viscous electrolyte used as part of the reference design helps to greatly slow down the ingress of process liquids through the diaphragm. The end result is longer sensor life, quicker response, and less error due to poisoning and clogging effects.

WHAT MAKES POLYMER-FILLED SENSORS DIFFERENT?
-
Single Pore Concept
Instead of a traditional porous diaphragm, polymer sensors use a single pore junction. This design allows 2000 larger contact area for the electrolyte and is extremely difficult to clog.
-
Polisolve (Plus) Electrolyte
Polymer electrolytes are stable and extremely viscous. This combination greatly slows ingress of process chemicals thus giving longer sensor life in difficult industrial applications.
-
Wide variety of industrial applications
The combination of polymer electrolyte and single pore junction allows these sensors to be used in applications from potable water to strong chemicals. No other sensor design provides this versatility.

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. -
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.

How to Measure Sensor A-length
Sensor A-length determines the insertion depth of the sensor. This article shows how this measurement is made for various styles of sensors. -
Powered vs. non-powered cables
Some sensors require standard cables while other sensors require power. Which cable should you use? This quick guide helps better answer these questions. -
