Abstract

The invention relates to an apparatus for electrically monitoring particles in an aerosol in non-collective manner such that a sample aerosol flow is arranged to flow through the apparatus, the apparatus (1) comprising an outer housing (A) for forming an outer casing of the apparatus. The apparatus (1) of the present invention further comprises a sensor housing (B) arranged inside the outer housing (A) and electrically separated from the outer housing (A) for receiving a sample aerosol flow and electrically monitoring particles in the sample aerosol flow.
