OMA-2000 Spectroscopic Gas Analyzer
The OMA-2000 spectroscopic gas analyzer is mainly composed of light source, spectrometer,
interface board and gray scale display module. It mainly realizes the measurement and display of
the density of SO

Each part performs functions as below:
z
Light source: The pulse xenon light source is adopted for supplying the particular band
of ultraviolet light source required in gas analysis.
z
Spectrometer: The holographic raster technology is used to acquire the spectrum of
measured gas.
z
Interface board: providing external ports for the analyzer.
z
Gray scale display module: performing signal processing, data calculation and
interaction of human-machine.
