NDIR CO2 sensor
The MTP50-A carbon dioxide sensor is based on the NDIR (non-dispersive infrared) principle. CO2 gas molecules can absorb infrared rays of a specific wavelength of about 4.26μm. When the light of this wavelength irradiates the gas sample, a corresponding light intensity change will occur. To calculate the concentration of CO2 gas, the MTP50-A dual-channel carbon dioxide sensor can resist interference from a variety of gases, has good gas selectivity, has built-in temperature compensation, and has higher measurement accuracy and stability.
