Aurora NE-300

Integrating Nephelometer

The amount of sunlight reaching the Earth’s surface, rather than being scattered back to space, is an essential parameter to accurately model the influence of aerosol scattering on the Earth’s radiative balance.

The Acoem Aurora NE-300 contributes to this measurement by reporting both the integrated full and backscatter coefficients at 3 wavelengths.

3 Wavelength Integrating Nephelometer
with backscatter functionality

Using a LED light source, the Aurora NE-300 simultaneously measures at 450 nm (blue), 525 nm (green) and 635 nm (red) to enable wide and in-depth analysis of the interaction between light and aerosols.

The Aurora NE-300 includes backscatter measurements that allows both standard integrating measurements of 7 – 173° and also the backscatter 90 – 173°.

Key highlights:

High-powered LED light source increases measurement accuracy
Single light source & detector used for all wavelengths
Heat generated by the light source is reduced by using high efficiency LEDs & fans, minimising changes in sample RH
Easy automatic calibration ensures repeatability of measurement
Automatic optical reference calibration
Facilitates a wide measuring range (0 to 20,000 Mm-1).

Benefits

Internal sample pump & flow sensor for accurate flow control with the option for volumetric flow control
Improved calibration process with span & zero gas following the same path into the cell as the ambient sample
Simplified automatic calibration using internal valves, ideal for remote locations
Fully programmable span check, zero check, span adjust, zero adjust or full calibration
Internal sample pump & flow sensor for accurate flow control with the option for volumetric flow control
Internal sample heater with temperature or RH control, you can enable to eliminate the effects of humidity
24 VDC operation (120 W max with supplied mains power supply)
Fully integrated data logging of all parameters with storage to either USB or SD card for many years
Increased light source intensity & reduced truncation angle, lower instrument noise & decreased wall scattering from internal reflections compared to previous generation Aurora 3000
LED light source is guaranteed not to fail within 3 years, & often exceeds 5 years lifetime
LED light source uses the same light path for each wavelength ensures consistency of measurement, eliminating the need for multiple PMTs & band pass filters maximising light intensity
Storage & automatic backup of configuration & calibration files
Suitable for high-altitude applications.

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.

Applications

Backscatter & forward scatter studies
Scattering enhancement factor (e.g. in combination with the Acoem Aerosol Conditioning System ACS™ 1000)
Scattering Angstrom exponent calculations
Determination of single scattering albedo.
