Product Overview
The SX-GO2EGA Series is a galvanic electrochemical oxygen sensor. Oxygen is reduced at the working electrode and an oxidation reaction occurs at the counter electrode, generating an electrical current. The output current is proportional to the oxygen concentration, allowing O₂ concentration to be determined from the measured current.
