Our expertise: the non-dispersive infrared spectroscopy technology

A non-dispersive infrared sensor consists of a detector that measures the amount of infrared light at a specific wavelength that is absorbed by a sample.

An infrared light passes through the chamber to the detector. The gas of interest causes an absorption of energy at a specific wavelength. This attenuation is measured by the detector to determine the concentration of the gas. The detector is preceded by a bandpass optical filter that eliminates all other wavelengths that the selected gas molecules may absorb.
