Overview

The GT/GG/GC Series from Sensorex provides high‑performance pH and ORP electrodes suitable for challenging industrial and process applications, including high temperature wastewater monitoring. The series leverages inert glass bodies and advanced reference designs (including double salt ring reference technology) to deliver consistent measurement stability and chemical resistance. Users can select from PTFE, open pore, or ceramic junction types based on the application’s particulate and chemical load. Multiple connector options (VarioPin or S8), temperature compensation choices, and selectable lengths make these electrodes versatile for integration with a range of instrumentation and installations. These electrodes are designed for accuracy, durability, and minimal maintenance, offering dependable operation over a broad pH and temperature range.
