QC-4SExplosion proof single 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, and stable performance. It is currently an ideal product among gas sampling instruments in China.
