ISFET pH sensor Durafet

compactnon-glass

Honeywell’s Ion Sensitive Field Effect Transistor (ISFET)-based Durafet non-glass pH sensor provides fast, accurate and dependable pH measurement in the most demanding applications. Honeywell’s Durafet pH electrode is an industrial, non-glass, unbreakable, Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor. The industry-proven pH electrode, with over 14 years of application experience, provides fast, accurate and dependable pH measurement in the most demanding applications.​​ What Is It? ​Durafet pH electrodes offer a reliable combination of measuring and reference electrodes and an integral automatic temperature compensator in a one-piece construction and are suited for varying pH and temperature ranges. Housed in a chemically resistant Ryton body, these electrodes serve the need of a variety of industrial or sanitary applications, including neutralization and reagent addition control. A sanitary Durafet III design is also available for food and dairy applications. Durafet III electrodes are designed with a rugged waterproof Vario Pin connector while Durafet II electrodes are available with a PC board connector. These electrodes are compatible with Honeywell’s entire instrumentation range including UDA2182, APT Series and DirectLine® sensor modules. How Does It Work? Durafet pH electrodes comprise a rugged, non-glass pH sensor that resists breakage in normal usage and offers up to 10 times faster responses than glass. The ISFET-based, solid state pH sensor emits a stable, low impedance signal, eliminating the need for frequent calibrations.
