GM35 CO, CO2, H2O, N2O in situ gas analyser

GM35 CO, CO2, H2O, N2O in situ gas analyser

GM35 – Multi-component gas analyzer for CO, CO2 and humidity (H2O)

Simultaneous or as individual measurement: the GM35 gas analyzer measures CO2, H2O and CO, or N2O, 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, precision, and short response time of the GM35 offer a key advantage for efficient control loops in all CO and CO2-generating processes.

Features:

  • 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 humidity measurement directly in the process
  • Provision of real humidity reference values
  • Unbiased measuring values due to in-situ measurement
  • Fast or short-term fluctuations in the process are being detected
  • Representative measurement by selection of an appropriate probe or cross-duct type

Applications:

  • Emission monitoring according to EN 14181, e. g., in power or cement plants
  • Control of the water injection upstream of the electrostatic precipitator
  • Monitoring of the combustion efficiency in hazardous waste incineration
  • Process monitoring in urea production
  • Tube rupture detection in heat exchangers
