BPIT, Inc. - Portable Aethalometer Model AE42

Portable Aethalometer Model AE42

By: Magee Scientific


The Aethalometer collects and analyzes aerosol particles continuously.  The aerosol-laden air stream is drawn through a spot on a filter tape at a measured flow rate.

  • AE42 2-Wavelength: Additional measurement at 370 nm designated as ‘UVPM’, interpreted as an indicator of aromatic organic compounds such as are found in tobacco smoke, wood and biomass-burning smoke, etc.
  • AE42 7-Wavelength: Simultaneous measurement at 7 wavelengths for studies of aerosol light absorption, atmospheric optics, radiative transfer, etc.: 370, 470, 520, 590, 660, 880 and 950 nm.
  • Portability: Self-contained instrument may be used on moving platform (i.e. car, bus, train, aircraft), or moved from one sampling location to another.
  • Specificity: No other aerosol species absorbs light even 0.001 times as much as Black Carbon in the visible range.
  • Timebase (User setting):
    • AE42-2: 1 hour to 1 minute
    • AE42-7: 1 hour to 2 minutes

DATA OUTPUT

Digital data is available via rear RS-232 (COM) port. Analog data is available via rear panel connector representing Black Carbon data as 0~5 volt DC signal, scalable in software.

 

DATA STORAGE

Data are written to removable CompactFlash® card once every timebase period.

 

DISPLAY AND INTERFACE

4-line display screen and status indication color LED’s. External detachable keypad.

 

ATTENTION REQUIRED

Instrument is completely automatic. No user attention is required during operation. Starts and runs automatically upon switching on. Internal battery provides approximately 3 hour run time during external power interruptions.

 

CONSUMABLES

Filter tape roll: 1 to 4 rolls per year, depending on BC concentrations.

 

PERIODIC MAINTENANCE

Recommended flow rate verification every three months, and cleaning the inlet assembly and analytical chamber once per year.

 

RELIABILITY

Aethalometers have been operating at hundreds of urban, regional, rural and remote locations on all continents, continuously since 1986.
