About This Product
Its large size makes this electroscope suited to classroom demonstrations of conduction, induction and Coulomb repulsion. When the plate takes up a charge, the metal vane swings away and the transparent scale shows the angle it has moved through. Ionising material can be placed in the chamber by sliding up the front glass window. Didactic Africa can supply and export the Large Needle Electroscope to schools, colleges and distributors in Togo, Italy, Colombia, Palestine and Eswatini.
