Backed by proprietary sensor technology and premium materials from Switzerland, Apera LabSen 841 Glass pH Electrode is designed for high-precision pH measurement of strong alkaline solutions (10-14 pH).
LabSen HA Glass Membrane – better accuracy and repeatability in strong alkaline solutions (10 to 14 pH), minimizing alkaline errors.
Built tough – The hemispherical glass membrane is 10 times stronger than traditional glass membranes, highly resistant to general impact, saving the electrode from accidental damage.
Silver Ion Trap Reference System – On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clog.
The electrode uses a standard 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.
