LabSen 853-S pH/temp. electrode is designed for high-accuracy pH measurement of highly viscous samples such as coatings, syrups, resin, glue, and etc.


The pre-pressurized structure allows the electrolyte to stably flow out even in highly viscous samples so as to ensure reliable measurements.


LabSen S-type glass membrane - 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.
