LabSen 841 Combination pH Electrode

Apera Instruments, AI3145, LabSen 841 Professional Combination pH Electrode for Strong Base SolutionsBacked by proprietary Swiss sensor technology and materials, the LabSen 841 Professional Combination pH Electrode/Probe is designed for pH measurements for strong base solutions (10-14 pH).Special Glass Membrane- The LabSen 841 pH Electrode/Probe 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/Probe 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.The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511, SX811, PH700, PH800, PC800, PH820 and PC820. Temperature sensor is not built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.Features:Proprietary pH sensor technology and materials from SwitzerlandUnique LabSen H glass membrane, which has a faster response rate, better repeatability in strong base solutions (10-14 pH)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 sulfideStandard BNC Connector.
