Try a REFEX probe in your plant and see the REFEX difference firsthand.

REFEX™ pH Sensors manufacture many varied pH sensor types, for many industrial processes, and for general purpose applications. Using the unique non porous REFEX™ reference system, REFEX offers the first to last, in quality, long life, low maintenance, stable readings and accurate pH measurements. REFEX™ can fabricate sensors that will retro-fit to your existing systems and housings. 

REFEX reference junctions are manufactured from an electrochemically conductive, salt loaded, polymeric matrix. When installed in an electrode, there is no porous junction to allow liquid contact between process fluids and the internal (sealed for life) Ag/AgCl reference half-cell. REFEX provides a stable mV output for measurement and ensures that process fluids do not poison or deplete reference cell electrode or electrolyte.

REFEX continues to perform even when completely coated as long as the coating remains wet and is conductive. Even when severe coating of the sensor inevitably slows electrode response, pH measurement remains accurate. Proven applications range from clean, cold river water to crude oil, sewage sludge and nasty chemical streams – all are solved with a REFEX reference interface.

The REFEX electrode is the reliable sensor the market has been waiting for – almost maintenance free with exceptionally long life and superb stability.
