Principles of NDIR Gas Sensors

HOME | TECHONOLOGY | PRINCIPLES OF SENSOR


	How does a non-dispersive infrared (NDIR) gas sensor work? -Using the characteristics of different gas molecules absorbing infrared rays with specific wavelengths, NDIR sensors measure the ratio of absorbed infrared rays and compute the density of gas (e.g. CO2 absorbs 4.26㎛ , and CO absorbs 4.64) -NDIR is contactless and highly accurate while having an extensive longevity. -Previously only used in manufacturing highly-priced measurement instruments,, NDIR technologies have been recently applied in mass-producing low-cost CO2 sensors for everyday use.
