QC-2The series dual gas path atmospheric sampler is a conventional instrument used for collecting gas samples. It consists of an air pump, a flow meter, a time control circuit, an undervoltage indicator circuit, and a dual-purpose AC/DC power supply. The vacuum pump is a diaphragm pump, which has the advantages of high pumping pressure, strong load capacity, stable flow rate, and low noise. This instrument has a compact structure, small size, light weight, is easy to carry, easy to operate, sturdy and durable, stable performance, and is equipped with a sturdy and durable triangular bracket. It is currently an ideal product among gas sampling instruments in China.
