QC-1S Atmospheric SamplerCompact structure, small size, light weight, easy to carry, easy to operate, sturdy and durable, stable performance, it is currently an ideal product among gas sampling instruments in China.QC-1S Atmospheric SamplerIt is a conventional instrument used for collecting gas samples, consisting of an air pump, a flow meter, a control 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.

Main features:

• Actual flow rate under negative pressure of 4500Pa is greater than 1L/min
• There is a filter element inside to prevent particulate matter from being sucked into the pump
• Voltage undervoltage indication accompanied by buzzer alarm
• Digital display time
• Dual use of AC and DC
