Mercury Instruments has specially designed the Mercury Stack Gas Monitor SM-4 for precise and reliable measurement of very low Hg concentrations in stack gases with a complex matrix containing SO2, NOx, HCl and others.

Typical fields of applications include:
Emissions monitoring for facilities of the 13. and 17. BImSchV
Coal fired power plants
Waste incineration plants
Sewage incineration plants
Cement kilns
Survey of general Hg emissions as well as efficiency monitoring of mercury reduction techniques
Thermal treatment of contaminated soils, hazardous waste, etc.
Metallurgical facilities with potential Hg emissions
