Field of application
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
Device properties:
No gas sampling, no gas transport, no gas conditioning
Up to four measurands at the same time, plus process temperature and pressures
Numerous independent measuring ranges with consistent accuracy
Automated self-test function (QAL3) without test gases
Overpressure encapsulated type Ex-zone 2
Benefits
Nearly uncompromised measured values measured directly in the gas duct
Short-term process deviations can be measured
Representative measurement by selection of cross-duct or measuring probe type
Fast on-site service possible due to modular design
Long maintenance-free intervals
Cost-effective in-situ gas analyzer — Ex-type also available
Low cost of installation and operation, no test gases required
