QC-3The Type 1 single gas path atmospheric sampler has a LCD digital display time function, which is used to collect gas samples in atmospheric or working environments(Mainly used in high traffic sampling)The conventional instrument 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 advantages of high pumping pressure, strong load capacity, stable flow rate, and low noise. This instrument is compact in structure, small in size, light in weight, easy to carry, easy to operate, sturdy and durable, with stable performance. It can be widely used in metallurgy, mining, chemical industry, building materials, casting, power and environmental monitoring, health and epidemic prevention and other departments. It is currently an ideal product among high flow gas sampling instruments in China.
