    SA Aerosol station

    The SA environmental monitors is used for continuous measurement of aerosol activities in all gaseous effluents. It can be fully integrated into environmental radiation monitoring systems.

    The SA aerosol station is designed to complete gamma radiation monitoring systems in environment networks, where continuous monitoring of the particulate with nuclide identification is required.

    It combines β & γ aerosol activites and spectrum measurement within the environment. The station aimed at monitoring outdoor particulate activities as part of a national or regional environment network, around nuclear facilities and nuclear sites.

    The SA sation is existing in 2 versions:

    • The SA 200 version is equipped with a strong pump system allowing a high air flow rate for very accurate measurements.
    • The SA 210 version is designed for situations requiring autonomous monitoring autonomous from main supply. It has a low power pump incl. battery pack modules, and performing a lower flow rate.
