Durafet pH Sensor

Field of Application :

The Honeywell Durafet pH Sensor is a non-glass, Ion Sensitive Field Effect Transistor (ISFET)-based electrode designed for fast, accurate, and reliable pH measurement in demanding industrial and sanitary applications. With over 14 years of proven performance, it is ideal for industries requiring break-resistant, low-maintenance, and long-lasting pH measurement solutions.

What Is It? :

The Durafet pH sensor integrates:

• A solid-state ISFET pH sensor that eliminates fragile glass electrodes
• A reference electrode for stable readings
• An automatic temperature compensator for precise measurement in varying conditions
• A chemically resistant Ryton body that ensures durability in harsh environments

Key Features :

• Break-resistant solid-state design prevents breakage common in glass electrodes
• Fast response time, up to ten times faster than traditional glass pH sensors
• Low-maintenance operation with a stable, low-impedance signal that reduces the need for frequent calibrations
• Flexible installation options with ¾” NPT threaded and 12-mm diameter designs for immersion or in-line applications
• Replaceable reference junction with a KCl gel-filled design that extends electrode lifespan and simplifies maintenance
• A sanitary version (Durafet III) designed for food and dairy industries, featuring a waterproof Vario Pin connector

Features :

Unlike traditional glass electrodes, the Durafet pH sensor uses an ISFET-based solid-state sensing element that detects pH changes rapidly and provides a stable, low-impedance signal. This design eliminates frequent calibration requirements, prevents breakage and handling issues in industrial environments, and ensures consistent and accurate pH measurement.

The sensor integrates seamlessly with Honeywell instrumentation, including the UDA2182, APT Series, and DirectLine® sensor modules.

Key Benefits :

• Increased Durability: Eliminates glass breakage risks
• Lower Maintenance Costs: Reduces frequent calibrations and replacements
• Enhanced Process Control: Faster response time for better operational efficiency
• Easy Installation: Simple replacement without the need for twisting cables
