The GM32 in-situ gas analyzer measures SO2, NO, NO2 and NH3, pressure and temperature in the gas duct. Direct, fast and without gas sampling and transport. Due to self-monitoring, the measured values are reliable. In case of a malfunction, an early warning will be shown. For emission measurement of SO2 and NO, the GM32 is tested for suitability according to European standard EN 15267. An Ex-type with extensive safety functions and sophisticated system technology is also available.
For monitoring and control in flue gas purification, such as denitrification plants, desulfurization plants and converters
Emissions monitoring according to EU directives or local regulations
