Aethalometer® Accessories & Routine Supplies
Magee Scientific can provide Aethalometer accessories and routine supplies such as those shown below. Please inquire with our sales team about your specific needs.
|Ambient Meteorological Sensor|
|The Ambient Meteorological Sensor is a non-aspirated unit which measures air temperature, relative humidity and barometric pressure. It uses a Pt100 element for Temperature ; a compensated solid-state capacitive sensor for Relative Humidity; and a piezoresistivepressure transducer for Pressure. The sensing elements are protected by a UV-resistant polymer shield. A cable (supplied) connects the sensor to the AE33, and its data is automatically imported and merged with the Black Carbon measurements.|
|All models of Aethalometer® use special reinforced quartz fiber or teflon coated glass fibre filter sampling tape. One roll of tape is installed in the instrument when shipped: it provides 1000 sampling spots and will last from months to years,
depending on use and aerosol concentration. We recommend an allowance
of 3 to 4 rolls per year for use in the most-polluted urban locations; 1
to 2 rolls per year in suburban or regional locations. |
Ambient atmospheres include suspended particles of large aerodynamic
size such as pollen, dust, etc. These particles are not strongly
optically absorbing and therefore do not interfere with the
Aethalometer® analysis: however, after lengthy use a deposit of dust in
the internal optics will degrade performance. To exclude large
particles, and provide analysis of a known respirable size fraction, we
recommend use of the ‘Sharp-Cut Cyclones’ designed and manufactured by
BGI of Waltham, MA, USA. At a given flow rate, these exclude particles
of aerodynamic size greater than a specified cut point. They are
attached directly to the Aethalometer inlet tube at the point of
BGI model SCC-1.828. Provides a cut point of 2.5µm at a sample flow rate of 5 LPM.
BGI model SCC-1.197. Provides a cut point of 2.5µm at a sample flow rate of 2 LPM, or 1µm at a sample flow rate of 5 LPM.
BGI model SCC-0.732. Provides a cut point of 1µm at a sample flow rate of 2 LPM.
BGI Inlet Kit
Inlet Kit contains PM-10 inlet head with jet inserts to accommodate
additional size selective capabilities including: TSP, PM-4, PM-2.5, and
PM-1. Designed to operate at 5 lpm for desired particle size cut point.
|For situations where the Aethalometer® must be shipped or transported
frequently, we recommend the use of Pelican® transit cases. These
provide internal padding; a sturdy waterproof exterior; and integrated
retractable handle and roller wheels.|
