Dekati® ELPI+ Low Pressure Impactor

Air particulate monitors

The Dekati® ELPI®+ (Electrical Low Pressure Impactor) is a particle size spectrometer that provides real-time particle measurements. An improved version of the popular and well characterised ELPI system, it lets you measure real-time particle size distribution and concentration in the 6 nm – 10 μm size range with a 10 Hz sampling rate.

The robust ELPI+ offers real-time stand-alone operation and wide sample concentration and particle size range for operation even in the harshest conditions. The ELPI+ can also be used for real-time particle charge distribution and gravimetric impactor measurements.

Acoem Australasia (Ecotech Pty Ltd) is the official distributor for Dekati fine particle measurement instruments in Australia and New Zealand.
