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.

Key highlights:

  • 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.

Benefits

  • Fully programmable integrated scattering over multiple angular sectors
  • High powered multi-wavelength LED light-source increases measurement accuracy
  • Higher flow available via the external pump & MFC option
  • Access to hundreds of raw measurement parameters for customised data analysis
  • Simplified fully automatic & scheduled calibration using internal valves, ideal for remote locations
  • Robust instrument for unattended operation
  • 24 VDC operation (120 W max with supplied mains power supply)
  • Automatic optical reference calibration
  • Internal sample heater with temperature or RH control, which you can enable to eliminate the effects of humidity
  • Increased light source intensity & reduced truncation angle, lower instrument noise & decreased wall scattering from internal reflections compared to previous generation Aurora 4000
  • LED light source is guaranteed not to fail within 3 years & often exceeds 5 years lifetime
  • Heat generated by the light source is reduced by using high efficiency LEDs & fans, minimising changes in sample RH
  • LEDs emit light at a specific wavelength eliminating the need for band pass filters
  • LED light source uses the same light path for each wavelength for consistency of measurement, eliminating the need for multiple PMTs & maximising light intensity
  • Storage & automatic backup of configuration & calibration files
  • Easily integrates into the Acoem Aerosol Conditioning System ACS™ 1000.

Options

  • Ambient Temperature & RH sensor for volumetric flow control
  • Roof flange, inlet extensions & rain cap with insect screen
  • Gas calibration kit & wall mount bracket
  • Annual service kit
  • Aerosol dryer
  • 20 lpm mass flow control option & external pump.
