Respirable dust sampler
M311079

 characteristics
Is widely used for all levels of health labor inspection agencies and factories, mines, metallurgy. Chemical industry can detect the concentrations of  total dust and respirable dust in the air  of workplace. The pre-sampling apparatus with automatic countdown time, overcome resistance ability, flow stability and accuracy, small size, light weight, DC power supply, easy to use and so on.

The main technical performance:
1. Sample flow:
Respirable dust sampling flow :10-30L / min
2. Operating voltage: 12V
3. System negative pressure:> 3000Pa
4. Timing range :0-959 min
5. Continuous working time:> 100min
6. The use of condition: -20 ~ 40 degrees relative humidity <85%
7. Measuring dust error: <2%
8. Noise <80dB
9. Respiratory dust particle symbol BMRC curve, respirable dust sampling head does not have the following characteristics of particle separation:
P = 1
Where: P --- permeability D --- aerodynamic diameter of dust:
D0 ---- 7.07
10. Weight: 2Kg
11. Sampling range: respirable dust, the dust
