LabSen 881 Glass-body pH Electrode for Low Temperature Solutions, BNC Connector

• Proprietary pH sensor technology and premium materials from Switzerland
• Built with a special low-resistance glass membrane for low-temperature solution testing
• LabSen L membrane with conical shape - fastest response and built tough, made for low-temp. solutions
• Silver Ion Trap Reference System+Protelyte Electrolyte

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 881 Glass pH Electrode is ideal for pH measurements of low-temperature solutions (down to -22 °F).

LabSen L Glass Membrane with conical shape - providing fast response even in low-temp. solutions thanks to its ultra-low resistance formula (<50MΩ), and yet highly resistant to general impact, 10 times stronger than traditional glass membranes.

Silver Ion Trap Reference System+Protelyte Electrolyte - LabSen 881 pH Electrode adopts a Silver Ion Trap reference system and Protelyte reference solution. On top of the Long-Life reference system, a silver ion trap is added to minimizing junction clogs, significantly extending the service life of the electrode.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is 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.
