Honeywell defines state-of-the-art pH measurement with the Durafet® pH electrode, a 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.

Honeywell’s 7777DVP Series of electrode mountings enables users to interface Durafet III pH electrodes to a process via a ¾” threaded connection by either submersing the electrode or mounting it into a ¾” threaded connection. Durafet pH electrodes are the first industrial ISFET-based pH sensors.

The Durafet III pH electrodes offer a reliable combination of measuring and reference electrodes together with an integral automatic temperature compensator PT1000 or NKT8.5K in a one-piece

corrosion-resistant molded Ryton body. Quick disconnect Vario Pin connectors enable easier installation and maintenance than with any other electrode available. The compact Durafet III electrodes with 3/4” NPT male connections are easily adapted for in-line mounting without O-rings or special seals.
