Infrared carbon dioxide measurement principle and advantages:
Infrared carbon dioxide sensor is the principle of infrared radiation emitted by infrared radiation radiation of carbon dioxide in the air, when the gas concentration changes, the carbon dioxide sensor to measure the infrared return wave will change.
Electrochemical gas sensor is the use of gas on the electrode electrochemical reaction (including oxidation and reduction), the detection of electrodes on the voltage or current to perceive the type and concentration of gas. Features are electrolytes (both liquid and solid) and electrolyte contact with the electrode.
Compared with the electrochemical principle, this infrared principle of carbon dioxide sensor, with temperature compensation, high reliability, and other gases will not produce cross-reactivity. Compared with electrochemical sensors, infrared sensors for up to 10 years of life, saving the carbon dioxide sensor aftermarket and maintenance costs.
