    Abstract

    In this study, a novel ultra fine particle measurement system using condensation and charging techniques was proposed. It consisted of the inlet / size separation part for selecting particles in the bounded-size range, a uniform growth unit for deriving the condensation of ultra fine particles, an aerosol charger for charging particles grown uniformly in the growth unit, a Faraday cage / ammeter part for measuring ultra low current about 10 -13 A induced by charged-particles collected on the filter in Faraday cage, and a communication network part for monitoring particle data in real time. The particle phenomena occurred in major components of the ultra fine particle measurement system was introduced and the ammeter circuit used in this work was described in detail. The performance of the prototype ammeter was comparable with a commercial one.
