Field of application
Simultaneous or as individual measurement: the GM35 gas analyzer measures CO2, H2O and CO, as well temperature and pressure – and it does this reliably, quickly, and economically. As an in-situ gas analyzer, the GM35 detects these gas components directly in the gas stream without gas sampling. Reliability, accuracy, and short response time of the GM35 offer a key advantage for efficient control loops in CO and CO2-generating processes.
Emission monitoring according to EN 14181, e. g., in power or cement plants
Control of the water injection upstream of the electrostatic precipitator
Device properties:
Dynamic humidity correction
Fast in-situ measurement directly in the process
Simultaneous determination of up to three gas components, temperature, and pressure
No gas sampling and conditioning
Gas testable version of measuring probe available
Integrated self-test and control functions
Benefits
Dynamic moisture measurement directly within the process
Provision of measured moisture reference values
Nearly uncompromised measured values thanks to in-situ measurement
Fast or transient process deviations are measurable
Representative measurement by selecting a suitable measuring probe or cross-duct type
