DT-2022B type vacuum box air bag sampler
The DT-2022B vacuum chamber air bag sampler utilizes polymer film air bags made of polyvinyl fluoride (PVF) and other materials. It employs a passive sampling method to collect various gases including environmental air, volatile organic compounds (VOCs), volatile halogenated hydrocarbons (VHHCs), total hydrocarbons (THCs), methane, non-methane total hydrocarbons (NMTHCs), and odorous gases from fixed pollution sources. This device is widely used in environmental protection, sanitation, labor safety, security inspection, military operations, scientific research, and educational institutions for the collection of diverse sample gases.
