QC-4S explosion-proof atmospheric samplerDetailed product description：

The QC-4S explosion-proof atmospheric sampler is a conventional instrument with LCD digital display time function, used for collecting gas samples in explosive gas environments. It consists of an air pump, a flow meter, a timing control circuit, and a power supply. The vacuum pump is a diaphragm pump, which has the characteristics of high pumping pressure, strong load capacity, stable flow rate, and low noise. This sampler has the advantages of electronic timing function, compact rhythm, small size, light weight, easy portability, simple operation, durability, stable and reliable performance. It can be widely used in metallurgy, mining, chemical industry, construction, casting, power and environmental monitoring, health and epidemic prevention and other departments. It is currently an ideal product among explosion-proof gas samplers in China.
