Dekati® PM10 Impactor


Manufacturer: DEKATI

A three-stage cascade impactor for determining particle gravimetric mass size distribution. The operating principle of the Dekati® PM10 impactor is based on inertial size classification and gravimetric or chemical analysis of the collected, size classified particle samples.


  • PM10, PM2.5 and PM1.0 measurements
  • Fulfills all requirements set in the ISO23210

  • Sampling in the impactor unit up to 200 °C.

DGI – Gravimetric Impactor


Manufacturer: DEKATI

A high sample flow rate cascade impactor for low concentration particle measurement applications. The DGI measures gravimetric particle mass size distribution of particles < 2.5 μm in five size fractions


  • High sample flow rate; each unit calibrated for 50, 60, 70, 80, 90 and 100 lpm
  • 47 mm substrates in the impactor stages

  • 70 mm filters at the final stage for smallest particle size fraction

Stack Impactors - Multistage Impactor for PM10 and PM2.5 mod. MSSI


Manufacturer: TCR TECORA

MSSI impactor is realized according to ISO23210 norm for the nozzle dimensioning. The impactor allows the simultaneous determination of total dust, PM10 and PM2.5 fractions (PM4 stage also available)


The impactor can be supplied with two different inlet cones to allow the vertical and horizontal sampling, depending on the stream direction into duct. The impactor is designed for a high sampling flowrate, about 2 m3/h, depending on emission characteristics, to reduce sampling time.
