The housing can contain a set of gas analyzer, computer etc in it.
Max. 100m extendable between housing and measuring probe.

Operating Principles

Respective molecules that constitute physical properties have their unique frequency of vibration, and only the infrared rays that correspond to the frequency of vibration are absorbed. Thus, the substance can be identified from the frequency distribution at the absorption peak. Infrared rays regarded as interference light by the interferometer are absorbed by the sample gas in the cell to obtain the frequency intensity specific to each molecule. The spectrum is obtained from the frequency intensity through the Fourier transformation, the mutual interference compensation and absorption band are selected, and then the gas is identified and the concentration is calculated from the library and CLS algorism.
