A measuring instrument of a charge distribution of aerosol particles has been designed and manufactured. Error factors relating to the design and natural electric field have been evaluated through numerical calculation based on the finite element method. The performance of the instrument has been also confirmed through experiments. The charge distribution of aerosol particles generated by a nebulizer or an ejector has been measured by the newly designed instrument. The experimental results showed that the electrification characteristics depended on the particle generation methods.
