In addition to the gas analysers, the systems usually also include flow meters, dust monitors and sensors for temperature and pressure; in all forming complete solutions providing full and continuous surveillance of the emissions from any industrial process.

The OPSIS systems for continuous emissions monitoring have a great advantage in a single gas analyser being able to measure a wide range of gaseous compounds, often in multiple gas ducts, providing a cost-efficient solution to the monitoring needs. A further advantage is the very low maintenance requirements, minimizing operating costs. The systems are easily integrated in existing process control systems, providing both real-time data and information for emissions reporting.

Cross-stack UV & FTIR DOAS Systems

OPSIS CEM systems measure multiple emissions or process gases in real time in situ. Using the DOAS (Differential Optical Absorption Spectroscopy) technique, the system is non-contact, with fast response.
One system can be configured to monitor NO, NO2, SO2, O3, H2S, NH3, CO, CO2, HF, H2O, CH4, Hg, HCl, Cl2, ClO2, CS2, Phenol, Formaldehyde, among other gaseous compounds.

A basic system includes an analyser, an emitter/receiver set, and an optical fibre cable.
