GM32 NH3, NO, NO2, SO2 in situ gas analyser

GM32 NH3, NO, NO2, SO2 in situ gas analyser

GM32 – Measure aggressive gases directly and quickly, even in ATEX zones

The GM32 in-situ gas analyzer measures SO2, NO, NO2 and NH3, as well as TRS components in Kraft pulp processes including pressure and temperature in the gas duct. Direct, fast and without gas sampling and transport. This means control systems are able to work with actual values in real time. Thanks to self-monitoring the measured value are reliable at any time. In case of a malfunction an early warning will be shown. For emission measurement of SO2 and NO, GM32 is tested for suitability according to European standard EN 15267-3. An ATEX version with comprehensive safety functions and sophisticated system technology is also available, as well as the GM32 TRS-PE (PE = Pulp Emission) for TRS measurement in Kraft pulp processes.
