Product Description

GP-V Valve Retractable pH Sensor

SKU: TT-GP-pH-2005

The GP-V Valve Retractable pH Sensor is uniquely designed to interface with our HOT TAP insertion valve retractable assembly, or sanitary assembly held in place by a tri-clover fitting.  Both methods allow for rapid insertion and removal from a process under pressure.

Our HOT TAP assemblies are a common feature in industries where direct access to the process is required inline or in-tank without interruption to service.  The RADEL body plastics provide superior resilience to physical impact and high abrasion, while the high capacity KYNAR reference provides both chemical resistance and temperate resistance to 105°C.  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.

The GP-V Valve retractable pH sensor is one of our most demanded configurations and meets the installation requirements of many applications. 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.

    • No hard wiring – plug-n-play connectivity
    • Sensor stores calibration data, analyser configuration and sensor history
    • Hot-swap for quick sensor change-out
    • No interaction with analyser – sensor data auto uploads

Digital Smart Sensor Technology (DSST)

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. On-board sensor memory allows the storage of calibration dataanalyser 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.
