The Signet 2724‑2726 pH and ORP electrodes feature a patented reference electrode design with large area PE reference junction and DryLoc connector with gold‑plated contacts. The robust Ryton threaded body and choice of flat pH, bulb pH, or flat ORP sensing elements provide broad chemical compatibility.

Optional HF version for traces of hydrofluoric acid (≤2%) at pH ≤6; LC version for low conductivity fluids (≥20 µS/cm). Quick temperature response with PT‑1000 or 3kΩ temperature sensor. 3⁄4″ NPT or ISO 7/1 R3⁄4 threads for standard pipe‑tees or GF Signet fittings.

Applications include water/wastewater treatment, neutralization systems, effluent monitoring, sanitization, pool/spa control, aquatic life support, process control, cooling towers. Operating temperature -10 to 85°C, 97% efficiency at 25°C.
