OCIEngine N2O
Miniaturized infrared spectroscopy sensors dedicated to nitrous oxide gas measurement.
What is it?
OCIEngine is an infrared spectrometer that measures Volatile Organic Compounds (VOC) in the air. It is specific to analyse a molecule of interest, such as nitrous oxide.
The measuring chamber of the sensor is crossed by infrared radiation. When the air is introduced into this chamber, the molecules of interest absorb a part of the radiation, which reduces the intensity of the optical signal. The concentration of the gas can therefore be deduced according to the Beer-Lambert’s physical law.
