YOKOGAWA PH8EHP-05-TN-TT1-N-GACN pH/ORP Sensor | High Temperature, PEEK, 3/4" NPT, Pt100, Double Junction, Preamplifier

YOKOGAWA PH8EHP-05-TN-TT1-N-GACN sensor specifications. High-temperature pH/ORP electrode, PEEK body, 3/4" NPT, Pt100, double junction ceramic, preamplifier.

Product Overview

The YOKOGAWA PH8EHP-05-TN-TT1-N-GACN is a high-performance combination pH or ORP (Redox) electrode engineered for demanding, high-temperature industrial applications. It features a PEEK (Polyetheretherketone) body, a 3/4" NPT process connection, an integrated Pt100 temperature sensor, and a built-in preamplifier. The "GACN" suffix denotes a double junction ceramic reference system, specifically designed to resist poisoning and extend service life in extreme process conditions.

Technical Specifications

Key Features

• High-Temperature Capability:​ Rated for continuous operation up to 130°C

• Double Junction Ceramic Reference:​ Provides superior resistance to reference poisoning from sulfides, proteins, and heavy metals

• Integrated Preamplifier:​ Enables reliable signal transmission over long cable runs (up to 100m)

• Built-in Pt100:​ Precision temperature sensor for accurate Automatic Temperature Compensation (ATC)

• Rugged PEEK Construction:​ Maintains integrity and chemical resistance at elevated temperatures

• Pressurized Reference:​ Maintenance-free, gel-filled system for stable performance

• 3/4" NPT Connection:​ Standard industrial threaded connection

• Direct Compatibility:​ Designed for YOKOGAWA pH/ORP analyzers (e.g., FLXA21, PH202G)

Applications

• High-temperature chemical processes (e.g., sterilization, distillation, reactor control)

• Wastewater treatment with hot effluent streams

• Pulp and paper digesters and bleach plants

• Food and beverage processing involving hot CIP (Clean-in-Place) cycles

• Any application requiring reliable pH/ORP measurement in media prone to reference electrode poisoning

Important Notes

1. This is a sensor only; it requires a compatible YOKOGAWA pH/ORP analyzer/transmitter.

2. The "GACN" suffix defines the high-performance double junction ceramic reference with preamplifier.

3. Regular calibration and cleaning are critical, especially in high-temperature or fouling services.

4. Ensure all wetted materials are compatible with the specific high-temperature process media.

5. The ceramic double junction is ideal for extending sensor life in challenging chemical environments.
