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

With our broad range of solutions Endress+Hauser has proven applicability in the entire power generation process, from gas flow to
combustion efficiency to emissions monitoring.
The GMK03 gas test unit is used to test the linearity of the measurement results of gas analyzers as required for a metrological quality test (e.g. for QAL2, QAL3). For this purpose, the GMK03 gas test unit can simulate several graded test gas concentrations with a single (suitable) test gas.
The air heater is used in in-situ and dust measurement devices. It serves to warm up the purge air in applications with gas temperatures close to water dew point or ambient temperatures down to –25 °C.
The repair service ensures that the functionality of the GM32 emission monitoring solution is restored quickly. The device is also given a general overhaul in order to prevent future failures.
