Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

Mar 21, 2017· NDIR CO2 Sensor. Non-dispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas.

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm-700nm).
