CHZ-15 gas negative pressure sampler

CHZ-15 gas negative pressure sampler summary：

The conventional method for many years collecting coal mine air downhole kind ofdouble chain ball bladder sampling, the sampling method has high labor intensity, the authenticity of the sample, not security and other aspects of the shortcomings. CHZ-15 gas automatic negative pressure sampler as a replacement products, has a series of advantages of sample, easy operation, labor saving, real time, safety, small volume,easy to carry, by the coal mine front staff welcome.
