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
, CO, CO2
, HF, H2
, Hg, HCl, Cl2
, Phenol, Formaldehyde, among other gaseous compounds
A basic system includes an analyser, an emitter/receiver set, and an optical fibre cable.
The system has been tested and approved by TÜV
according to EN 15267, and a range of other international authorities
