Individual Dust Sampler

Individual Dust Sampler main technical parameters:

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)
