The complete, ready to use emissions analyzer SWG 100 CEM is the low cost solution
to be used with a wide variety of industrial emissions monitoring applications:
The MRU continuous emission monitoring analyzer SWG 100 CEM, is designed for use in the harsh industrial
environment of different combustion sites, where flue gas emissions must be continuously monitored.
The analyzer can be installed in outdoor or indoor locations, can sample dry or wet flue gas, pressurized or
low pressure flue gas, even from a long distance sampling point.
The analyzer system can be configured with different gas sampling probes and sampling lines to optimize the
sample gas preparation.
