Backed 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.
The electrode is backed up with a 6-month warranty by Apera Instruments.
