MRU SWG 200 Continuous Emission Monitor

The MRU SWG 200 continuous emission monitor is a cost-effective, reliable system for emission and combustion monitoring. The monitor is suitable for various industrial sectors, including diesel engines, methane/natural gas boilers, landfill gas/bio-gas CHPs, bagasse and biomass boilers, and many other industries.

The SWG 200 is housed in a IP54 aluminum cabinet with anti-corrosive red structural lacquer and monitored fan ventilation. It uses optimized NDIR technology with improved accuracy and without zero offset. It also features O2 measurement with an electrochemical or a paramagnetic sensor, automatic zeroing using clean ambient air, automatic calibration for up to four gas cylinders, a double stage Peltier gas cooler with two automatic condensate draining pumps, and cold/dry gas sampling with low sample flow volume of only 1 l/min. Various probes are available, depending on the condition of the gases to be analyzed.
