1. Product introduction
The sampler is equipped with two types of dust pre-trap, one is a total dust pre-trap for measuring the total dust concentration; the other is a pre-trap for measuring the concentration of respirable dust; The respiratory dust and non-respirable dust that are harmful to the human body are separated, and both respiratory and non-respirable dust samples can be collected at one time. The separation efficiency reaches the internationally recognized "BMRC" curve standard, which is a relatively reliable dust. separation device.
It is suitable for underground coal mines and other workplaces containing explosive dangerous gases.
