Aurora 2000
AURORA 2000 - PM Correlating Nephelometer
BENEFITS
  • Simplified automatic calibration using internal valves, ideal for remote locations

  • Fully integrated package including: internal sample pump, sample heater,
    internal calibration valves, zero air pump and 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 (45 watts max, 13 watts nominal)

 

The Aurora 2000 PM Correlating Nephelometer is part of the ‘new generation’ nephelometers using a single wavelength and a BETA monitor to measure aerosol light scattering and derive particulate concentrations.

 

The Aurora 2000 enables the calculation of a correlation factor based on a PM2.5 reference method which is then used to derive every minute a PM2.5 concentrations along with the usual light scattering. The correction factor can be entered manually or automatically derived from hourly averages from a continuous PM2.5 monitor.
