Outdoor Air ELPI™ (Electrical Low Pressure Impactor) is a modified version of the standard ELPI™ instrument.

DLPI (Dekati Low Pressure Impactor) is a cascade low pressure impactor to classify airborne particles into 13 size fractions. The size classification is made from 30 nm up to 10 µm with evenly distributed impactor stages.

DGI-1570 (Dekati Gravimetric Impactor) is a cascade impactor designed for measuring particle size distribution from engine exhaust.

Dekati PM10 impactor is a three stage cascade impactor for determining particle gravimetric mass size distribution.
