The Dekati® High Pressure Diluter DEED-300 is a two-stage dilution device for taking aerosol sample from high sample pressure such as pre-DPF conditions. The DEED-300 is designed especially for these conditions and it always keeps a constant dilution factor regardless of the sample pressure inside the tailpipe.

Total dilution factor in the DEED-300 unit is typically between 40 and 60 and it is individually calibrated for each unit for optimal results.


  • Aerosol dilution from high sample pressure conditions
  • Stable dilution for pre-DPF conditions up to 600 °C
  • Always constant dilution factor regardless of sample pressure
  • Sample temperature and pressure at ambient levels at the outlet of the DEED-300 system
  • Robust, stainless steel construction


  • Dilution device for conditions where sample pressure is higher than ambient pressure level
  • Application where the sample pressure is high such as different industrial and combustion process measurements
