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.
