GRIMM 7917
Emission sampling system (ESS)

For direct sampling of high-temperature aerosols from hot exhaust gas, e.g. from fireplaces, combustion processes or engine exhausts. Built for temperatures of up to 500 °C (932 °F). 

  • Sampling from hot gas with temperatures up to 500 °C
  • Heated sampling probe to prevent particle formation
  • Stable and reproducible dilution ratios
  • Optional with one or two dilution stages
  • Integrated filter, dryer and activated charcoal absorber
  • Compatible with GRIMM SMPS+C and SMPS+E systems
  • Engine exhaust studies
  • Characterisation of burners
  • Monitoring emissions from domestic heating
  • Measurements in stacks
  • Optimization of burner chambers and combustion processes
  • Technical data
