Optical Monitoring System

Total System Supplier

At Opsis we concentrate on optical measurements because the technique is flexible and provides rapid measurements that allow the quantification of several gases simultaneously with great reliability. Our product uses the DOAS (Differential Optical Absorption Spectroscopy) technique. Also, Opsis offers a wide range of additional equipment such as compact analysers, O2 meters and particulate monitors. Furthermore we have developed powerful software tools for environmental management.

 
  

DOAS Technique

In a DOAS system, an emitter projects a beam of light to a receiver. In an industrial application the light beam crosses a stack or duct. The light is transferred to the Opsis analyser through a fibre optic cable. Here, specific gases will absorb light from known parts of the spectrum, both in the UV, visible and IR wavelength ranges. The absorption is recorded by using a computer-controlled spectrometer. The computer also registers results for immediate display or future analysis.

The Opsis data, together with other information, is stored in the analyser and is available for rapid processing, analysis and presentation through the user-friendly Opsis software packages.
