1. Product introduction
AKFC-92A mine dust sampler is a conventional instrument for measuring the concentration of floating dust in ambient air. It is composed of alarm circuit, safety power supply, etc. It is also equipped with a variety of dust pre-catchers. Among them, the whole dust pre-collector is used to measure the total dust concentration; the other is the impact pre-collector used to measure the concentration of respirable dust. It can collect both respirable and non-respirable dust samples at one time, and its separation efficiency reaches the internationally recognized "BMRC" curve standard. It is a relatively reliable and practical dust pre-separation device.
It is suitable for dust monitoring in industrial and mining enterprises, labor safety, labor hygiene and environmental protection departments.
