LabSen 831 Combination pH Electrode

Apera Instruments, AI3109, LabSen 831 Professional Combination pH Electrode for Strong Acid SamplesBacked by proprietary Swiss sensor technology and materials, the LabSen 831 HF pH Electrode Probe is designed for pH measurements for solutions containing Hydrofluoric acid (≥3pH), or other strong acid solutions.Special Glass Membrane- Unique LabSen HF glass membrane, which has a faster response rate, better repeatability in strong acid samples, and resistant to hydrofluoride corrosion.Silver Ion Trap Reference System- The LabSen 831 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.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 HF glass membrane, which has a faster response rate, better repeatability in strong acid samples, and resistant to hydrofluoride corrosionSilver 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.
