OPSIS System 400 - Cross Stack

The System400CS is based on a non-contact method, using an optical measurement path that operates across the duct. System400CS is based on Opsis UV/FTIR DOAS system giving fast response and best possible performance for all gases. The high resolution FTIR system is free from interference from all gases including water. The UV measurements of NO, NO2, SO2 and Hg gives outstanding performance. One analyser cabinet can operate several measurement paths using an optical multiplexer. A single System400CS will measure all relevant gases for CEM applications such as NO, NO2, SO2, NH3, CO, CO2, HCl, HF, N2O, CH4, H2O, O2 and Hg. The in situ method measures the gas component inside the stack without use of a sampling system. The in situ system is analysing several cubic metres of stack gas every minute, thus giving a fast and representative result. The in situ system can be installed in all applications including high dust, high temperature and sticky gas conditions. A built-in web interface and web logger allows the user to control the system via internet and to manage the measurement without loss of data.
