Description
Gastec CE Oxygen Sensor
Gastec CE Oxygen Sensor (frequently referenced in conjunction with Gastec’s specialized continuous air-monitoring lines and handheld gas sampling systems) is a electrochemical gas sensing module designed for measuring ambient Oxygen (O2) concentration to prevent asphyxiation and monitor confined space safety.
Unlike single-use colorimetric glass detector tubes (such as Gastec Tube 31B), the CE-series electrochemical oxygen sensor provides continuous real-time digital measurement of oxygen levels in percentage volume (O2%).
Core Operating Principle
Gas Diffusion: Ambient oxygen diffuses through a gas-permeable membrane into an internal cell filled with a specialized electrolyte solution.
Electrochemical Oxidation/Reduction: Oxygen undergoes a reduction reaction at the sensing electrode (cathode).
