U-RANGE 2000

Combination of Fidas® 200 and U-SMPS systems for particle measurements in the size range of 4 nm to 40 µm

The Palas U-RANGE combines two systems for continuously measuring airborne particles in a size range of 4 nm to 40 μm (depending on the configuration).

The U-SMPS is a standard system for exact measurements of nanoparticle size distributions. Aerosol particles are selected in the classifier (DEMC) according to their electrical mobility and then counted by a condensation particle counter (UF‐CPC). Prof. Wiedensohler (IfT Leipzig, Germany) developed the algorithm used by Palas for the inversion of the measured data to yield the particle size distribution for the U-SMPS.

The Fidas® 200 is a fine dust measurement system for ambient air quality measurements for regulatory purposes. It uses the recognized measurement technology of optical light scattering of single particles and is equipped with an LED light source with stable output and a long lifetime.
