Process pH Electrode Materials

In Ryton® (PPS) designs, materials wetted by the sample include: Ryton® (PPS), polyethylene, glass, SS, O-rings made of Viton®, and for ORP electrodes--platinum.

In CPVC designs, materials wetted by the sample include: CPVC, polyethylene, glass, O-rings made of Viton®, and for ORP electrodes--platinum.

Material wetted by the sample in Kynar® (PVDF) designs include: Kynar® (PVDF) , glass, Viton® O-rings, and for ORP electrodes--platinum.

Ryton® (PPS), CPVC and Kynar® (PVDF) electrode pipe Tee fittings are not interchangeable.

The general purpose process electrodes are made of Ryton® (PPS) or epoxy. Mounting glands for these electrodes are available in glass filled polypropylene. Other materials of the electrode in contact with the sample include silicone, nylon, and glass.

The laboratory pH and ORP electrodes are made of either epoxy or glass. The glass electrodes will also have ceramic in contact with the sample. The epoxy electrodes will have silicone, nylon, and glass in contact with the sample.

Additionally, some unique sensors are constructed from highly specialized engineering materials such as PEEK®. With this wide range of available materials Sensorex has the right electrode for your application.
