GP8 High Temperature pH & ORP Sensor


The GP8 High-Temperature pH & ORP Sensor is made with PEEK body plastics to resist high process temperatures up to 135°C continuous operating temperature. With an optional upgrade to the reference, we can achieve continuous temperature exposure of 150°C.

All Turtle Tough high-temperature sensors are equipped with fast response temperature compensation to guarantee high calibration accuracy. At these temperatures, slow response to temperature can introduce significant measurement errors that are reduced by high accuracy and rapid response temperature compensation.

The PEEK body has the highest of all chemical and physical resistance properties. The high capacity KYNAR reference provides chemical and temperate resistance. Utilising our proprietary toughened glass the sensor is ideal for slurries and abrasive media as well as being capable of resisting acids or fluorides that may chemically attack the glass. For operators who are prone to bashing the sensor against hard surfaces or smashing the glass during maintenance, the optional ULTRA TOUGH break-resistant glass is an excellent option.

The GP8 High-Temperature pH Sensor is a popular configuration and as such this sensor is available in many optional configurations including high impact break resistant glass, ultra high temperature, dissolved gas and volatile organic solvent resistant, high HF acid resistant, brine and extreme dehydration resistance.

The Turtle Tough GP8 High-Temperature pH Sensor is ideal for applications such as industrial autoclaves, ammonium nitrate plants, sugar refining and extraction. Any measurement where aggressive chemical cleaning is needed to remove fouling or low maintenance operation is required with minimal cleaning and recalibration

Not suitable for use in low conductivity, steam sterilization or steam type processes.

Digital Sensor Technology (-D)

This sensor is available with our digital smart sensor technology. This plug and play sensor has a quick connect fitting, eliminating the need for hard wiring to the analyser. Onboard sensor memory allows the storage of calibration data, analyser configurations and sensor service history. This allows the sensor to be conveniently maintained and calibrated off-site or in the laboratory and pre-programmed with calibration data and analyser configurations. This stored information automatically uploads to the analyser upon connection and eliminates the need for any interaction with the analyser, greatly simplifying the change-out of sensors. A service log stored on the sensors is ideal for maintenance and quality assurance records.
