Model 5012 Multi Angle Absorption Photometers from Lear Siegler Australasia measure the levels of black carbon in the atmosphere. Black carbon comes from activities such as traffic, fire, and the use of coal and biomass fuels.
It is thought that these soot emissions contribute to climate change by absorbing sunlight, heating the air and making the atmosphere less stable.
Model 5012 Multi Angle Absorption Photometers measures atmospheric Black carbon loading. It does this by using a radiative transfer scheme to particle loaded glass fibre filters.
The black carbon content of the aerosols are continuously determined by simultaneously measuring the optical absorption and scattering of light by the particles collected on the filter tape.
Model 5012 Multi Angle Absorption Photometers provide an accurate and true measurement of the black carbon content by combining these two techniques.
