Applications areas
SAFETY
In industry, analyzing air gases is vital for worker safety. Detecting toxic or flammable gases promptly prevents accidents, ensuring a secure work environment.
INDUSTRIAL PROCESSES
In some industrial processes, gases are essential and need to be measured continuously to ensure that operations run smoothly. 
HEALTH
Our sensors offer a significant advantage by measuring VOCs in exhaled air and analyzing specific health parameters.
EXPERTISE
Our expertise:
the non-dispersive infrared
spectroscopy
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.
