Overview

Infrared photometry analyzer uses high-performance light emitting diodes (IR-LED) and thermal micro radiators which are suitable to gas measurement technology. It has high stability and a low detection limit. In the spectral range from 2 μm to 12 μm, carbon dioxide(CO2), carbon monoxide(CO), hydrocarbons(CmHn) and nitrous oxide(N2O) can be measured.

Principle

Infrared photometry analyzer uses broadband radiation sources (thermal emitters). This radiation immediately reaches the measuring cuvette. There, specific spectral ranges are absorbed from the broadband spectrum of the radiation source. The measuring detector which contains at least 2 separate channels, is located at the end of the measuring cuvette. In the simplest case the measuring channel has an interference filter placed in front of the detector. The reference detector also has an interference filter in front of the detector, but with a spectral transmission range (approx. 4 µm) where no absorption takes place. Afterwards a detector measures the specific radiation absorption. The evaluation electronics use the two signals to calculate the gas concentration in the measuring cuvette. Alternatively, a detector with several measuring channels can be placed at the end of the measuring cuvette, so that 3 components to be recorded simultaneously.
