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
Soil moisture conditions, often referred to as soil moisture, are critical to agricultural production. Soil moisture is directly related to the growing conditions of crops and is one of the key environmental factors that determine the health of crops.Knowing the exact level of soil moisture and its...
