  • SELF-CALIBRATING GAS SENSOR
    Publication number: 20110197649
    Abstract: A self-calibrating gas sensor comprises a steady current measuring gas line composed of valves, pumps and a current-type electrochemical sensor, and a coulomb analyzing gas line composed of said valves, said pumps, said current-type electrochemical sensor and a sample chamber. The two gas lines can be interchanged between measurement and analysis by controlling valves. The sensor can measure gas concentrations, and self-calibrate its sensitivity without the need of standard gases for external calibration.
