Monitoring nephelometer Aurora™ 2000

The Aurora 2000 PM2.5 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. Features AUTO CALIBRATION 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 & data logger INTERNAL SAMPLE HEATER 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 % ) ENERGY 12 VDC operation (45 W max, 13 W nominal) REMOTE CONTROLE Remote control through serial interface Light Source The Aurora 2000 can be equipped with any one of the following LED 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). Configurations Aurora 2000 PM2.5 Nephelometer — manual correction factor configuration In applications where the aerosol chemistry is stable, a correction factor can be manually entered which then provides excellent results with minimal maintenance and a high degree of correlation.
