EmailThe NOX-200A is a pretreatment device for NOx analyzers developed by our company for ambient air quality monitoring and dilution method measurement in continuous emission monitoring systems (CEMS). The converter can almost completely convert NO2 in flue gas to NO based on the technical principle of catalytic conversion combined with temperature control technology.
Catalytic conversion principle, high conversion efficiency:
Stable and reliable temperature control;
Basically no interference with gases such as SO2 , O2 , etc.
Fast response time;
Long service life
Since this converter can convert nitrogen dioxide into nitric oxide, it can be used in the integration of new equipment for nitrogen oxide analyzers and in the modification of operating equipment to improve detection accuracy. It can also be used in NOx separation and conversion equipment.
