DS-2108 M Dust Meter is a machine which is used to directly test the environment pollution levels in the atmosphere (The mass concentration of PMIO ) and can directly reveal the results of PM10 and PM2.5. This machine is developed by our company and South Korea DongSong, and its performance has achieved the international advanced level, which has been the specified products for the government of the South Korea to purchase and is widely used in public places , shopping malls, Subway stations and crowded areas for air quality monitoring.
The working principle for the instrument is that a laser light source irradiates on the particles; then the solid state detector detects the scattered light; and at last, the optical signals are turned into electrical signals. The mass concentration of the particles is calculated out according to the strength of the electrical signal.
