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

Air quality sensors are used to detect airborne pollutants such as the familiar PM10 and PM2.5 particulate matter. These particles can affect our health, especially PM2.5 because it is very fine and can penetrate deep into the lungs. The Air Quality Index (AQI) uses the concentration of these partic...
