Individual dust sampler

Main technical parameters of Individual dust sampler:

The Individual dust sampler is a test instrument that simulates the average concentration of dust in the air inhaled by a worker in a shift.

1. Sampling flow rate: Respirable dust sampling: 2L/min (fixed flow rate)

2. Sampling flow error: ≤3%FS

3. Sampling flow stability: The sampling flow stability of the sampler within 8 hours is ≤3.0%FS 

4. Load capacity: ≥1000Pa

5. Continuous working time: ≥8h

6. Working noise: ≤65dB (A)

7. Flow meter accuracy: not less than level 2.5

8. Sampling time error: ≤0.1% within 5 minutes

9. Average flow velocity of sampling port: 0.5～4.0m/s

10. Air tightness: The sampling head and flow meter of the sampler are maintained at a pressure difference of (1000-1100) Pa for 1 minute, and the pressure change shall not exceed 100 Pa.

11. Sampling accuracy error: ≤10%

12. Explosion-proof type: mining intrinsically safe type ExibI (150℃), suitable for flammable and explosive workplaces and coal mine underground sampling.

13. Sampling efficiency: in line with the "BMRC" sampling efficiency curve;

14. Overall dimensions: 120×80×42 (mm)

15. Weight: 450g
