The DGI Impactor  (Dekati® Gravimetric Impactor) is a high sample flow rate cascade impactor designed for measuring gravimetric particle size distribution of particles smaller 2.5 µm. In a standard DGI setup, particles are size classified into 5 size fractions with impactor stage cutpoints of 2.5, 1.0, 0.5 and 0.2 µm.

If detailed information on the size distribution is not needed, some of the impactor stages can be removed from the DGI assembly.


  • Particle size distribution in five size fractions <2.5 µm
  • High sample flow rate (each unit calibrated for 50, 60, 70, 80, 90 and 100 lpm)
  • Easy-to-use stainless steel construction


  • Any application where particles exist in its operational size range (<2.5 µm) and high amount of sample is available (sample flow rate 50 – 100 lpm)
  • Air quality studies
  • Engine exhaust measurements
