working principle

Spectral absorption method indicates that many gas molecules exhibit characteristic absorption in the infrared band. According to Lambert Beer's law, the characteristic absorption intensity is directly proportional to the gas concentration. The THA100 infrared gas analyzer adopts this principle and belongs to the NDIR (non dispersive) infrared gas analyzer. It can be used to continuously analyze the concentration of one or several gas components to be tested in mixed gases. The THA100 infrared gas analyzer adopts mature and reliable analysis methods in the field of gas analysis, using MEMS infrared light source and dual channel infrared detector.
