Infrared Measurement Principle (NDIR) - ecom

NDIR analysers are particularly suitable for the determination of the concentration of carbon monoxide, carbon dioxide or hydrocarbons in a gas. Components of this process are a source of infrared radiation, an irradiated tube (cuvette) with the gas to be analysed, a wavelength filter and an infrared detector. The gas which has to be analysed is pumped into the sample. To ensure the sensor ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

NDIR Gas Measurement Principle. To measure the gas concentration with precision, you need two thermopile sensors and an infrared light source. One sensor serves as reference to monitor the variation of IR source output due to source aging, power variations, etc.. The other sensor is equipped with a gas-specific narrow band optical filter.
