Ecotech Aurora 3000 integrating nephelometer

Monday, 16 August, 2010 | Supplied by: Ecotech Pty Ltd

Backscatter measurements are now supplied standard for the Aurora 3000 integrating nephelometer.

These nephelometers are a series of instruments used for measuring the scattering of light (scattering coefficient) of aerosols in the atmosphere. This information is useful for determining the influence of atmospheric aerosols on the global radiation balance, its impact on global dimming and climate change.

The backscatter feature of the nephelometer is achieved through the use of a backscatter shutter mounted on the light-source housing inside the cell. This shutter moves between two locations in and out of the optical path of the light source (90 to 180°) within the light sources Lambertian distribution. The position of the backscatter shutter is controlled to within ±0.09° and can be adjusted to achieve other cutoff angles if required, for more advanced analysis of backscatter.

Several different configurations of integrating nephelometers are available, including a single wavelength, multiple wavelength and a PM2.5 correlating version for use in air-quality monitoring networks.
