GB/T20964-2007 "Dust Sampler"

scope of application：

Suitable for short-term, high flow sampling of respiratory dust and total dust in dusty working environments. Especially suitable for use in coal mines and other workplaces containing explosive gases.

main features：

1. This sampler adopts an (intrinsic safety type) explosion-proof design, which is particularly suitable for use in coal mines and other workplaces containing explosive gases;

2. The protection level of the sampler casing is IP54. The casing is made of high-strength ABS engineering plastic and has been specially treated for moisture, dust, and static electricity prevention;

3. The sampler has small airflow pulsation, high load capacity, and stable flow rate;

4. The sampler has a small operating volume, light weight, and is easy to carry;

5. The panel adopts PVC film switch, which has the characteristics of simple operation, safety and reliability, and easy maintenance;

6. The separation efficiency of the dust sampler for respiratory dust fully meets the requirements of the "BMRC" international standard curve, and can scientifically reflect the quality of respiratory dust for dust collectors and the degree of harm of dust in different workplaces;

7. Has a coal safety explosion-proof inspection certificate.
