EXM400
The Model EXM400 gas analyser is specifically designed for stack emission, deNOx and desulphurisation systems, engine exhaust and other chemical processes.
The measurement principle is based on the UV absorption spectrum of gases in the UV range.
The periodic structure of the absorption bands coming from the different levels of rotational energy of the gas molecules is analysed by performing a Fourier Transform on the absorption spectrum with a high speed DSP (Digital Signal Processor).
The EXM400 performs Fourier transform in the UV range by solid state optics and electronic circuits resulting in an economical instrument for measuring ammonia. The selectivity of the analyser is guaranteed by the typical UV spectrum of each gas.
