3-wavelengths integrating nephelometer

The Ecotech Aurora 3000 nephelometer simultaneously measures at 450 nm (blue), 525 nm (green) and 635 nm (red) to enable analysis of the interaction between light and aerosols. The nephelometer includes measurements that allow both standard integrating scattering measurements of 9 – 170° and also the backscatter 90 – 170°. Scattering and back scattering properties are measured continuously.
