Honeywell defines state-of-the-art pH measurement with the Durafet® pH electrode, an industrial, non-glass, unbreakable, Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. This industry-proven pH electrode, with over 14 years of application experience, provides fast, accurate and dependable pH measurement in the most demanding applications. The Durafet electrodes include a connector, enabling easy and reliable electrode replacement without twisting of cables. Durafet III electrodes are designed with a rugged waterproof Vario Pin connector. Durafet II electrodes have a PC board connector. Durafet electrodes offer a reliable combination of measuring and reference electrodes together with an integral automatic temperature compensator in a one-piece construction. The compact industrial Durafet electrodes are available in two basic designs: a ¾" NPT male threaded connection or a 12mm diameter electrode (Durafet II only). The type of design is based on the customer's desired mounting. A sanitary Durafet III design is also available for food and dairy applications.
