Aurora 1000

Integrating Nephelometer

Easy to use and maintain, the Aurora 1000 lowers the cost of ownership for aerosol light scattering, visibility and particulate monitoring instrumentation.

The Aurora 1000 uses a single wavelength LED for light scattering coefficient and visibility measurements.

Acoem, through collaboration with globally renowned atmospheric research institutes, now provide the scientific community with the most advanced commercially available nephelometers

Using a single wavelength LED light source

The Aurora 1000 can be equipped with any of the following light sources:

  • 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).


  • Simplified automatic calibration using internal valves, ideal for remote locations. Fully automatic zero check or adjust, automatic span check or automatic zero & span check available in intervals of 1, 3, 6, 12, 24 hrs or weekly
  • Fully integrated package including: internal sample pump, sample heater, internal calibration valves, zero air pump & data logger
  • Internal sample heater with temperature or RH control, which can be enabled by the user to eliminate the effects of humidity (RH: < 30 to < 90 % )
  • 12 VDC operation (60 W max, 13 W nominal)
  • Holds up to 61 days of 5 minute data averages or 2 days of 1 min data
  • Free Airodis™ demo version & firmware upgrade software supplied on USB or via Internet
  • Remote control through serial interface
  • Our LED light source is guaranteed not to fail within 3 years & often exceeds 5 years life time
  • Heat generated by the LED light source is a fraction of that generated by a flash lamp, minimising changes in sample RH
  • LEDs emit light at a specific wavelength eliminating the need for band pass filters


  • Automated ball valve (sample bypass)
  • Exhaust tubing kit
  • External pump controller kit & pump
  • Roof flange kit & rain cap with insect screen
  • Gas calibration kit
  • Wall mount bracket.


  • 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.
