Electroscope. This extra-large electroscope is ideal for classroom demonstrations of electrostatic principles such as conduction, induction and coulomb repulsion. light-weight metal vane is used as pointer in the electroscope. The lightweight metal blade deflects when the electroscope plate is charged. transparent scale is provided to measure the angle of the deflection. The front glass window slides up to allow insertion of ionizing material in chamber. This electroscope comes with two accessories: an electrophorus disc and spherical electrode.
