SensaAir® Technology
The unique SenseAir Technology from ETM Pacific is based on the well known principle of infrared (IR) absorption of radiation called the non-dispersive infrared (NDIR) technique. This technique relies on the fact that molecules absorb light (electromagnetic energy) at spectral regions where the radiated wavelength coincides with internal molecular energy levels in the sensor systems.

By detecting the amount of light absorbed, within just a narrow band width that coincides with the resonance wavelength of the species selected, one gets a measure of the number of molecules, free from interference of other species.
