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 gaserous 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 and MCERTS according to EN 15267, and a range of other international authorities.
