Procédé et dispositif pour la mesure de la concentration en nombre et du diamètre moyen de particules d'aérosol

摘要

Aerosol particle number concentration measurement involves electrically charging an aerosol by diffusion charging, to create charged aerosol particles, for making measurement of a diffusional precipitator current. An influence current arising in a diffusional precipitator is compensated. The compensation of the current includes measuring an influence current in an additional electrode. The precipitator is a plate precipitator. An independent claim is also included for a device for measuring the number concentration and the average diameter of particles of an aerosol.
