LabSen 881 Glass-body pH Electrode for Low Temperature Solutions by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 881 Glass Combination pH Electrode is ideal for pH measurements for low-temperature solutions (down to -22 °F).

Special Glass Membrane - The LabSen 881 pH electrode adopts a low-impedance 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 a 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 MP511, PH8500, PH850, PH700, 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.

• Proprietary pH sensor technology and materials from Switzerland
• A special low-impedance glass membrane is adopted, which is especially suitable for low-temperature sample testing
• LabSen conical sensor tip - fast response rate, high repeatability, and built tough
• Standard BNC Connector
• 6-Month Warranty fulfilled by Apera Instruments
