Product Overview
The SX-GSO2TSA Series is a potentiostatic electrochemical sulfur dioxide sensor. Sulfur dioxide and oxygen undergo oxidation–reduction reactions at the working electrode and counter electrode, respectively, generating an electrical current. The output current is proportional to the sulfur dioxide concentration, allowing SO₂ concentration to be determined from the measured current.
