We evaluate the size distribution of fine water droplets produced by electrostatic atomization using a differential mobility analyzer (DMA) and a condensation nucleus counter (CNC) . Broad size distribution with the peak of mobility diameter of around 15-20 nm is observed for the neutralized polydisperse water droplets. The number of charge is analyzed using a tandem DMA system. The water droplets are highly charged depending on the particle size. The number of maximum electric charges is 14, which is well below the Rayleigh limit.
