Using a single wavelength LED light source

By collaborating with globally renowned atmospheric research institutes, Acoem provides the scientific community with the most advanced commercially available nephelometers.

The Aurora NE-100 is equipped with a three wavelength light source. Any one of the following wavelengths can be selected:

  • 450 nm (blue) for fine & ultra fine particulates
    (wood fires, automobiles)
  • 525 nm (green) for visibility
  • 635 nm (red) for large particulates (e.g. pollen, sea salt). Note: If using the 635 nm wavelength, Acoem recommends adding the wide bandwidth PMT option for minimal noise.

Applications

  • Visibility measurements (airports, city pollution, AAQMS)
  • Dust/sand storm monitoring & early detection networks
  • Bushfire pollution monitoring & early detection networks
  • PM2.5 mass measurement correlation studies.

Benefits

  • Internal sample heater with temperature or RH control, which you can enable to eliminate the effects of humidity
  • Internal sample pump & flow sensor for accurate flow control with the option for volumetric flow control
  • Simplified automatic calibration using internal valves, ideal for remote locations
  • Fully programmable span check, zero check, span adjust, zero adjust or full calibration
  • 24 VDC operation (100 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
  • Free Airodis™ demo version supplied on USB or via internet
  • Storage & automatic backup of configuration & calibration files
  • Increased light source intensity & reduced truncation angle, lower instrument noise & decreased wall scattering from internal reflections compared to previous generation Aurora 1000
  • 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.

Options

  • Wide bandwidth PMT for 635 nm measurement
  • Ambient Temperature & RH sensor for volumetric flow control
  • Annual service kit
  • 20 lpm mass flow control option & external pump
  • Roof flange, inlet extensions & rain cap with insect screen
  • Gas calibration kit
  • Wall mount bracket.
