[0002] A dust sampler is a portable device for collecting dust samples in dusty air. It measures the dust concentration in the air. In addition to the needs of safe production management, it also provides a scientific basis for the research of dust prevention, dust reduction and dust removal measures. Measuring dust with a sampler is a recognized method with high accuracy. It is widely used in health monitoring and evaluation of disease prevention, environmental monitoring, labor protection, safety supervision and other departments. It is specifically used to measure the average dust concentration in the air in the workplace of production teams.
