  • Visibility measurements (airports, city pollution, AAQMS)

  • Dust/sand storm monitoring and early detection networks

  • Bushfire pollution monitoring and early detection networks

  • PM2.5 mass measurement correlation studies


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.


Using a single wavelength LED light source, the Aurora 1000 can be equipped with any of the following light sources:

  • 450nm (blue) for fine and ultra-fine particulates

  • 525nm (green) for visibility

  • 635nm (red) for large particulates
