Special Glass Membrane – The LabSen 841 pH electrode adopts a special H glass membrane, which has better accuracy and repteatability in strong base solutions; the hemispherical sensor is also built tough and highly resistent to general impact (completely different from the traditional fragile glass bulb membrane). Silver Ion Trap Reference System – The LabSen 841 pH electrode adopts a 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 Ft The 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 (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation. The electrode is backed up with a 6-month warranty by Apera Instruments.
