HTabsOverviewThe AE33 Aethalometer® is designed to integrate into common air quality monitoring station set ups. Model AE33 offers measurement at 7 wavelengths enabling comprehensive examination of the deposited aerosol including size distribution, physical properties and identification of primary components. Aerosol loading effects are eliminated via the Dual SpotTM measurement method and real time calculation of loading compensation parameters. Key features of the AE33 include: Measurement of seven wavelengths - 370, 470, 520, 590, 660, 880 and 950nm, Time resolution to 1 second, Real-time DualSpot™ Technology for compensation of loading effect Dynamic active zero check and automatic stability check, Optical Calibration and Validation capability (more info) Network ready, standard 19” rack mount with touchscreen display Internal sample pump with electronic flow control BIomass burning indicator Accessories include neutral density optical filter validation kit, CO2 sensor, ambient meteorological sensor and aerosol inlet dryer SpecificationMeasurement Parameter: Black CarbonSpecification: Product name AETHALOMETER® AE33 Manufacturer Magee Scientific Description MEASUREMENT PRINCIPLE Continuous collection of aerosol on filter with simultaneous measurement of attenuation of transmitted light at wavelengths of 370, 470, 520, 590, 660, 880 and 950 nm. Black Carbon concentration measurement is defined by the absorption measurement at 880 nm. Multiple wavelength analysis for source apportionment (identification of biomass smoke), studies of aerosol light absorption, radiative transfer, atmospheric optics. High data rate capability for source and emissions testing. DUALSPOTTM TECHNOLOGY Simultaneous analysis of light absorption by aerosol deposits collected on 2 spots in parallel at different loading rates*. Mathematical combination of data yields Black Carbon result independent of ''spot loading effects'' and provides additional information about aerosol composition.
