ZR-3930B type ambient air particle sampler Introduction
ZR-3930B type ambient air particle sampler (A type, 10 film; B type, 20 film) (automatic film change), used for air automatic station PM10, PM2.5 data comparison quality control. It is equipped with a standard 16.67L/min cutter (compatible with US EPA standards). It is mainly used to sample PM10/PM2.5 (fine particles) in ambient air, which can automatically change the membrane and automatically sample unattended all-weather.
