Meteomodem - Aerosol Counter Sensor - Brochure

This new original and versatile aerosol counting instrument doesn’t use any lens, only a laser beam and two scattering angles, respectively at 12° and 60 ° allowing to determine the concentration of aerosols (numbers of aerosols per cm3) for 19 size classes between 0.2 and 50 micrometers. The combination of these two angles allows also to identify the typology of the aerosols according to 5 main families of particles (Carbons, Droplets, Ice, Salt and Minerals). The instrument can be used for several purposes:  to document the physical properties of aerosols in the lower and middle atmosphere during specific events like pollution peaks, transported sands, volcanic ashes, and/or for long-term monitoring purposes.
