About This Product
Static charge is produced by friction between the moving rubber belt and two rollers, then removed from the belt by a metal gauze and stored in the dome. The 4 mm socket in the base can either support a conducting sphere on a cranked rod or take a wire connection to a separate conducting sphere. When the generator is not in use, the cover provided keeps it free from dust.
