Inhalable dust sampler technical parameters:
inhalable dust sampler is used to measure the concentration of inhalable dust, collect the inhalable dust on the filter membrane, then weigh and calculate the concentration of inhalable dust.
1.Sampling flow rate: 5-30 L/min, 5-25 L/min, 10-25 L/min, 1-10 L/min (flow rate optional) Respirable dust sampling flow rate: 20 L/min
2.Sampling flow error: ≤±3%FS
3.Sampling flow stability: sampling flow stability of the sampler within 60 minutes ≤ 3.0% FS
4.Load capacity: ≥200Pa
5.Continuous working time: ≥100min
6.Working noise: ≤75dB(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.Ambient temperature: -10~40℃ Relative humidity: ≤95%
12.Explosion-proof type: Mining intrinsically safe type ExibI (150°C), suitable for flammable and explosive workplaces and underground sampling in coal mines.
