High-Quality Continuous Flue Gas Analyzer for Sale

Depended on years of laser gas analyzer and flue gas analyzer research experience and combined with practical experience of thousands of successful application cases, analyzers provided by continuous emission monitoring system suppliers like ZETIAN have derived multiple types (standard type, low emission type, ultra-low emission type, and customized type) to meet different index requirements in different working condition.

UV DOAS technology. The optical technology platform consists of a light source, gas chamber, optical fiber and spectrograph (including the diaphragm, a holographic grating, linear array detector) and other optical components.

Ultraviolet light emitted by light source enters the gas chamber by an optical window and absorbed by measured sample gas flowed through the gas chamber. The light carrying sample absorption information will be gathered by the lens and coupled into an optical fiber and then transmits into spectrometer through fiber. After light splitting and photo-voltaic conversion, the gas absorption spectrum is obtained.

The corresponding component concentration in the gas can be calculated by analyzing the spectrum.

Note: the difference among standard analyzer, low emission analyzer, and ultra-low analyzer is the different optical path length of gas chamber; for standard online gas analyser, it adopts dual lens collimation system with 0.25m optical path; for low emission analyzer, it adopts multiple return structure with 1m optical path; for ultra-low emission analyzer, it uses white cell structure.
