Abstract
A generator of water aerosols that produces almost uniform droplets in the above-micron range is described. The operational behavior and the effect of various parameters of the apparatus is reported. Attention is also paid to the rarely discussed electric charges of the particles, which can be neutralized at will.
The aim distribution of the droplets is determined both by a rate of fall and a light attenuation/weight method that cheek reasonably well; the number concentration is derived from the size distribution and the weight of the particles per unit volume while the charge is found from the mobility in a horizontal electric field.
