The DT-2022B Vacuum Chamber Airbag Sampler utilizes polyvinyl fluoride (PVF) polymer film airbags to collect environmental air and fixed-source exhaust gases through passive sampling. It effectively captures volatile organic compounds (VOCs), volatile halogenated hydrocarbons, total atmospheric hydrocarbons, methane, non-methane total hydrocarbons, and odorous gases. This device is widely used by environmental protection agencies, health authorities, labor departments, safety inspection units, military organizations, research institutions, and educational institutions for various sample gas collection applications.
