Apera AI3145 LabSen 841 Glass-Body pH Electrode for Strong Base Solutions - Impact-Resistant Sensor with BNC Connector - Ideal for Laboratory Testing, Chemical Analysis & Industrial Applications

Backed by proprietary Swiss sensor technology and materials, Apera LabSen 841 pH Electrode is designed for pH measurement of strong base solutions (10-14 pH). Special Glass Membrane – a special H glass membrane is adopted for better accuracy and repeatability in strong base solutions; the hemispherical sensor is also built tough and highly resistant to general impact (completely different from the traditional fragile glass bulb membrane). Silver Ion Trap Reference System – On top of the Long-Life reference system, a silver ion trap is added to prevent the junction being blocked by silver sulfide. Housing Material: Lead-free glass; Temp. Sensor: No; Junction: Ceramic; Reference: Silver Ion Trap; Electrolyte: 3M KCL; Length: 120mm; Diameter: 12mm; Membrane Shape: hemispherical; Range: 2-14 pH; Temp. Range: 0 to 100˚C (32 to 212˚F); Connector: BNC; Cable: 3 Father electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to realize temperature compensation. The product is CE and RoHS certified, and is manufactured under an ISO 9001: 2015 certified quality system.
