Abstract

The present invention is related to a device for measuring the mass of particles of an aerosol per volume unit. It comprises a solid measuring body, measuring means for measuring the resonance frequency of said solid measuring body, means for generating a flow of air loaded with particles and for directing said air flow toward a planar receiving electrode and means for electrically loading said particles with a polarity opposed to that of the planar receiving electrode.
