LabSen 863 pH/temp. electrode is designed for high-accuracy pH measurement of corrosive and high-temp. solutions such as electroplating solutions.


The PHY membrane is the most robust membrane of the LabSen series, highly resistant to chemical corrosions and high temperaure up to 130˚C, maximizing the reliability and service life of the electrode in complex and high-temp. solution testing.


Compatible with all Apera Instruments meters with BNC and RCA connectors such as PH910, PH9500, PH850, PC8500, and PH820. May NOT work with other brands' meters because the thermistor might be incompatible.
