3. Product Features

Compared with the QC-2 series sampler, this instrument has the remarkable characteristics of independent control and separate timing, which is especially suitable for the occasions where different gases are sampled at the same time. The instrument is composed of two air pumps to form an independent gas circuit system, which can collect two kinds of gas samples or balance samples at the same time, and can also collect one kind of gas sample separately, which makes the sampling work convenient, fast and reliable. At the same time, the instrument has the advantages of high pumping pressure, strong load capacity, stable flow, and low noise.

The instrument is compact in structure, small in size, light in weight, easy to carry, easy to operate, sturdy and durable, and has stable performance.
