| Dust pollution control drew more attention in modern world environment protection.Developing new method which monitored dust pollution and studied dust distribution and change rule is important in environment protection.After analyzing new monitor dust technique from domestic to overseas, we find Light Scattering Method performs best in on-line test dust state. From light scattering phenomena and Mie scattering theory, we design portable optics dust tester and introduce main part of the tester and part of program. The tester can test low density dust, test range from a few mg/m3to500mg/m3.Portable Optics Dust Tester is a wide range of applications in industry dust emission. |
