DESCRIPTION

AirTrack-Mobile, is a transportable Monitoring Station made of two sub-units, installed on a trolley for easy transport and operability. The QDU is made of two Modules, an Alpha/Beta Continuous Aerosol Monitor with an optional a wide-range Gamma dose rate monitor, and a Meteorological Station. A compact collapsible mast for weather sensors mounting (3mt when deployed) and integrated LTE/3G data modem completes the QDU assembly.

The basic QDU includes only the Aerosols Monitor unit, the other modules that are part of the QDU may be added optionally, depending upon additional needs of the Client.
