其他检测技术
Catalytic technology
A sensor that converts the sensed concentration of combustible gas into a usable output signal by utilizing the resistance changes generated by the combustion of the contact surface between combustible gas and catalytic material.
Infrared technology
Infrared gas sensor is a gas sensing device that selects absorption characteristics based on near-infrared spectra of different gas molecules, identifies gas components and determines their concentrations using the relationship between gas concentration and absorption intensity (Lambert Beer law).
electrochemical techniques
Electrochemical gas sensor is a detector that measures the concentration of the target gas by measuring the current through oxidation or reduction of the target gas at the electrode.
