Plastic pH sensor water ph sensor


The PH-5019 pH electrode (pH sensor) consists of a pH-sensitive membrane, double-junction reference GPT medium electrolyte, and a porous, large-area PTFE salt bridge. The plastic case of the electrode is made of modified PON, which can withstand high temperature up to 80°C and resist strong acid and strong alkali corrosion. It is widely used in wastewater treatment and fields, including mining and smelting, papermaking, paper pulp, textiles, petrochemical industry, process of semiconductor electronic industry and downstream engineering of biotechnology.
