摘　　要：A system for measuring the electric properties of single aerosol droplet is designed and applied to the NaClO4 aerosol droplet in different relative humidity (RH). The conductance and capacitance are ob-tained within the whole RH range, especially in the supersaturated state which cannot be acquired from the bulk solution. These results reflect the situation of ions in the droplet macroscopically and supply useful information for other relative study fields, such as crystallogeny and aerography.A system for measuring the electric properties of single aerosol droplet is designed and applied to the NaClO4 aerosol droplet in different relative humidity （RH）.
