- Perfect for hands on experience in the classroom
Eisco Labs Needle Electroscope
This electroscope is great for hands on experience with electrostatic principles in physics classrooms and labs. The sheet metal walls of the electroscope are attached to a plastic base and top. Front glass window slides up to allow insertion of ionizing material in chamber. A light-weight metal vane is used as a pointer in the electroscope. This light weight metal blade deflects when the electroscope plate is charged. A graduated scale is provided to measure the angle of the deflection.
. Fitted with 4mm socket. Assembled, the electroscope measures 4 x 3.75 x 2.25 inches.
