The Aurora 4000 builds on the same three wavelength capabilities as the
Aurora 3000. This device provides measurements of light scattering
within up to 18 user selectable angular sectors, using varied
backscatter shutter positioning. This can be used to determine the phase
function of aerosols, which is crucial to climate research and
modelling. Despite its sophisticated capabilities, the Aurora 4000
maintains the same ease of use, maintenance and calibration as the rest
of the Aurora range.

Wide measurement range (0.1 to 20,000 Mm-1)
18 angular sectors; full integrated scattering, as well as integrated
scattering of up to 17 different angular sectors from 10˚ to 90˚ through
to 170˚
Raw measurement counts available for customised data analysis
NEW Automatic ball valve option: protect against contamination of a
common sampling manifold, bypassing the instrument during calibration
NEW Mass flow control option enables flow to be controlled in
conjunction with an external pump
