Backed by proprietary sensor technologies and premium materials from Switzerland, Apera LabSen 821 pH Electrode is designed for professional pH measurement of milk, cream, yogurt, sauces, and other liquids containing proteins.
Silver Ion Trap Reference System+Protelyte Electrolyte - LabSen 821 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 caused by proteins, significantly extending the service life of the electrode in protein solutions testing.
LabSen S-type hemispherical glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage.
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.
