Applications areas


The measurement of certain gases is necessary for the safety of people


Certain gases must be monitored during the ripening, harvesting, storage and transport of fruits and vegetables to avoid any quality deterioration.


Our sensors allow to monitor certain parameters of individuals.

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.
