The Aurora 2000 PM Correlating Nephelometer is part of the ‘new generation’ nephelometers using a single wavelength and an 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.
