Flagship three wavelength
polar integrating nephelometer
The Aurora NE-400 Polar provides measurements of integrated light scattering between 7° – 173°, with the user able to select multiple backscatter angles between the 7° to 90° starting angle of integration.
The instrument simultaneously measures at 450 nm (blue), 525 nm (green) and 635 nm (red), using the proven LED light source to enable wide and in-depth analysis of the interaction between light and aerosols.
These measurements can contribute to determining the phase function, defined as the amount of light scattered as a function of the scattering angle. The phase function is a key parameter to accurately model the influence of the aerosol scattering on the Earth’s radiative balance.
- Wide measurement range (0.1 to 20,000 Mm-1)
- 18 angular sectors fully-integrated scattering
- Automatic bypass ball valve protects against contamination of a common sampling manifold during calibration
- Mass flow control enables flow to be controlled in conjunction with an internal pump.
