Individual Dust Sampler

Individual Dust Sampler main technical parameters:

Individual Dust Sampler is an instrument for measuring the average concentration of dust in the air of a work shift, which is suitable for underground sampling in coal mines.

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 rate at sampling port: 0.5～4.0m/s

10.Air tightness: The sampling head and flow meter of the sampler are kept under 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°C), suitable for flammable and explosive workplaces and underground sampling in coal mines.

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

14.Dimensions: 120×80×42 (mm)

15.Weight: 450g
