Aerosol neutralizer 5523

GRIMM 5523
63Ni aerosol neutralizer

This aerosol neutralizer works based on the radioactive decay of 63Ni and is compatible with GRIMM SMPS+C and SMPS+E systems. It provides all benefits of radioactive source based neutralizers, however does not require a special handling licence*. 

Functionality: Aerosol neutralizer based on 63Ni

*Note: The regulations concerning radiation protection (also for X-ray radiation) differ between countries and the individual federal states. To obtain information on the handling regulations, please contact the competent authority in your country or federal state.
