Dekati® PM10 Impactor


The Dekati® PM10 Impactor is 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. This impactor has cutpoints of 10, 2.5 and 1 μm making it an ideal choice for PM10, PM2.5 and PM1.0 measurements. The impactor is manufactured of stainless steel enabling direct sampling from high temperatures and heating the impactor unit up to 200 °C. The Dekati® PM10 Impactor fulfills all requirements set in the ISO23210 standard for determination of PM10 and PM2.5 mass concentrations in stationary sources.
