Backed by proprietary Swiss sensor technology and materials, the LabSen 881 Professional Combination pH Electrode is ideal for pH measurements for low-temperature solutions (down to -30°C/-22 °F).
Special Glass Membrane – The LabSen 881 pH electrode adopts a low-impedence glass membrane, which is especially suitable for low-temperature sample testing. The conical sensor tip is highly resistant to general impact (completely different from the traditional fragile glass bulb sensor), and has faster response rate and better repeatability.
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 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.
