Dekati® High Temperature ELPI®+ (HT-ELPI®+) is now available also with the Dekati® High Resolution software for even more detailed particle size distribution measurements. The HT-ELPI®+ enables direct real-time measurement of high temperature aerosols and the new software increases the size resolution to 500 size channels from 6 nm up to 10 µm. The new configuration can be connected directly to the emission source and is ideal for measurement of combustion generated particles without the need of complication sample conditioning or dilution systems.
