Introduction:
GP‑100 PTFE pH Sensor is an industrial online pH combination electrode without temperature compensation. Constructed with full PTFE wetted parts, it is specially designed for harsh corrosive working conditions including high‑temperature, strong acid and strong‑alkali media. It adopts low‑impedance sensitive glass membrane, circular anti‑pollution PTFE diaphragm and gel electrolyte salt bridge. Maintenance‑free design, no electrolyte refilling required. Suitable for scenarios where temperature fluctuation is less than 10℃. Supports piping or submersible installation.
Key Features:
Maintenance‑free gel electrolyte, no need for electrolyte refilling
Gel electrolyte salt bridge effectively prevents electrode poisoning
Anti‑pollution circular PTFE diaphragm, anti‑clogging for long‑term operation
Low‑impedance sensitive glass membrane, fast response and good thermal stability
Full PTFE wetted material, excellent corrosion resistance for strong acid / alkali / high‑temperature fluid
Dual 3/4" BSP thread, support piping‑mount or submersible installation
No built‑in temperature compensation, fit for environment with temperature variation ≤10℃
