- Proprietary pH sensor technology and materials from Switzerland
- Unique LabSen pH 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 sulfide
- Standard BNC Connector
- 6-Month Warranty fulfilled by Apera Instruments
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 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 – 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 PH850, PC850, PH8500, PC8500, PH700,PH910, PC910, PH950, PC950, PH800, PH800, PC800, PH820 and PC820. The temperature sensor is not built-in. Users need to have a separate temperatureprobe (ex: Apera Instruments MP500) to enable ATC or manually input temperatureto realize temperature compensation.
The electrode is backed up with a 6-month warranty by Apera Instruments.
