PTC works with Magee Scientific and AethLabs to supply the Aethalometer®, which is an instrument that uses optical analysis to determine the mass concentration of “Black Carbon” particles collected from an air stream passing through a filter.

These particles are directly emitted to the air during all combustion, but are primarily associated with coal or diesel smoke. They adversely affect public health; contribute to local and global climate change; and reduce visibility. Aethalometers are used by air-quality monitoring programs; public-health protection agencies; research laboratories; and community groups.

Aethalometer data contribute to an understanding of the composition and sources of air-pollution particles; the effects of poor air quality on public health; and the effects on local weather and global climate change.

The Aethalometer technology is available on different chassis and platforms: Rack Mount, Portable, Modular, High Range, and Optical Transmissometer. The aethalometer is also offered in two configurations of optical analysis: “dual wavelength” (infra-red 880 nm for Black Carbon; ultraviolet 370 nm for aromatic organic compounds) and “seven wavelength Spectrum” (7 sources from 370 nm to 950 nm).

Rack Mount Aethalometers®

The Aethalometer® is the most widely used instrument for the Real-Time Measurement of Aerosol Black Carbon ('BC' or 'EC'). The Aethalometer is fully automatic and completely self-contained and has been used by scientists for more than 15 years on all 7 continents.

Portable Aethalometer®

The Portable Aethalometer® is a compact version of the standard Aethalometer® that includes an internal battery for mobile use and GPS option for integrated mobile tracking. Like the standard Aethalometer, the portable is fully automatic and completely self-contained.

Major applications for aethalometer are:

  • Ambient air quality monitoring
  • Occupational exposure
  • Indoor air quality
  • Emissions monitoring

AethLabs microAeth® Model AE51 Aethalometer®

AethLabs microAeth® Model AE51 is the world's first ever real-time, pocket-sized Black Carbon aerosol monitor. This palm-size instrument is small enough to be worn by a person in order to measure the real-time concentration of black carbon which a person may be exposed to. The microAeth incorporates the same Aethalometer® measurement technology which has been used worldwide for over 25 years, all in a package that can fit in your pocket.
