The QC-2A atmospheric sampler is a conventional instrument used to collect gas samples in atmospheric or working environments. It consists of two independent gas path systems composed of two suction pumps, which can simultaneously collect two types of gas samples or collect balanced samples. It is fast and reliable for sampling work. This sampler can be widely used in metallurgy, mining, chemical industry, construction, casting, power and environmental monitoring, health and epidemic prevention and other departments. It has the advantages of electronic timing function, compact rhythm, small size, stable and reliable performance, and is currently an ideal product among domestic atmospheric samplers. Meanwhile, due to the use of a powerful pump in the suction pump of the QC-2A atmospheric sampler, it overcomes greater resistance and makes sampling more convenient
