The Aurora-3000 is the instrument of choice when analysis is required on a number of different contributors to air pollution or for studies regarding global warming using backscatter.

Using an innovative LED light source, the Aurora-3000 simultaneously measures at 525nm (green), 450nm (blue) and 635nm (red) to enable wide and in-depth analysis of particulate matter. The Ecotech Aurora 3000 includes backscatter measurement that allows both standard integrating measurements of 9-170° but also just the back scatter 90-170°.

The Aurora 3000 allows the analysis of parameters (backscatter/forward scatter) involved in climate studies and specifically global radiation balance. Furthermore the Aurora 3000 is relevant for general air quality studies such as pollution sources comparison.
