Rack Mount Aethalometer® Model AE33





The ‘Next Generation’ Aethalometer®, Model AE33, incorporates scientific and technical advances designed to offer improved measurement performance, user features, communications and interface, and the ability to perform routine performance tests to verify correct operation. Most importantly, the new instrument incorporates the patented DualSpot™ measurement method. This provides two significant advantages: elimination of the changes in response due to ‘aerosol loading’ effects; and a real-time calculation of the ‘loading compensation’ parameter which offers insights into aerosol optical properties.

 
 

The novel Aethalometer AE33 was developed within an Eurostars project with Swiss partners Paul Scherrer Research Institute and inNET, who extensively tested the instrument in the lab and field studies.
   

The project was awarded as a Success story on the Eurostars joint programme webpage. Please check this link for the details.
 

Rack Mount Aethalometer® Models AE22 and AE31



The Rack Mount Aethalometer® models are constructed in a standard 19-inch enclosed chassis. These Aethalometer models are most commonly used in air monitoring network stations, providing continuous unattended operation. The instruments simultaneously sample and measure the mass concentration of black carbon particles in the air. A digital display/keypad combination interface is used to operate, monitor, calibrate, and service the instruments. The measurement data are stored within the instruments on removable media (compact flash). An analog channel outputs a signal for communicating the real-time mass concentration to an external data logger. This analog channel can also be programmed to communicate an instrument status condition.

Rack Mount Aethalometer® Model AE22 2-Wavelength 
(NOT IN PRODUCTION AMY MORE)
The Rack Mount Aethalometer Model AE22 measures the light absorption of carbon particles at two wavelengths: 880 nm (IR), quantitative for the mass of ‘Black’ or Elemental Carbon; and 370 nm (UV), indicating the presence of aromatic organic compounds such as are found in wood smoke, biomass-burning smoke, and tobacco smoke. The Real-time measurements can be made with time resolution from one second to one hour.  Performing the 2 wavelength measurement is important in determining the sources of airborne black carbon particles (ie. diesel exhaust vs. wood smoke combustion). The instrument is widely used in monitoring applications involving human exposure to localized, community-based sources of air pollution.

Rack Mount Aethalometer® Model AE31 7-Wavelength
(NOT IN PRODUCTION AMY MORE)
The Rack Mount Aethalometer Model AE31 measures light absorption by suspended aerosol particles at seven wavelengths, from 370 nm (UV) to 950 nm (IR).  Real-time measurements of particle concentrations can be made with a time resolution of two minutes to one hour.  Interpretation of the differences in optical response across the wavelength spectrum reveal information regarding aerosol size distribution, physical properties, and assist in identifying the primary components.  This instrument is widely used in monitoring studies involving large scale, regional air pollution problems.
