Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 851-1 Glass-body pH Electrode is designed for pH measurement of viscous samples such as skincare products, cosmetics, and coatings.

Silver Ion Trap Reference System+Protelyte Electrolyte - The LabSen 851-1 pH electrode adopts a Silver Ion Trap reference system and Protelyte reference solution, minimizing junction clogs.

LabSen conical glass membrane - large surface area rendering fast response, and is 10 times stronger than traditional glass membranes, saving the electrode from accidental damage.

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 MP500) to enable ATC or manually input temperature to realize temperature compensation.
