AR600 Series – Opsis Gas Monitoring System

Overview

In a DOAS system, an emitter projects a light beam to a receiver. In an industrial application the beam crosses a stack or flue duct. This absorbs light of specific gases from well-known parts of the spectrum, the ultraviolet, visible as well as infrared wavelengths. The light goes through the receiver and is transferred into Opsis analyser through an optical fibre cable. The absorption is recorded by a computer-controlled spectrometer. The computer also records the results either for immediate presentation or for future analysis.

The measurement data, along with other information, are stored in the analyser and available for fast processing, analysis and presentation using the user-friendly software packages from Opsis.
