Description:

Used to check the high voltage line and electrical equipment whether have power frequency with acousto-optic function, used with high voltage sources such as static electricity and electrostatic machines. The insulating tube is telescopic, convenient and safe for measuring. Come with an aluminum holder case and there is any foam in the case, to protect the electroscope well. Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force, the electric potential or voltage of an object equals its charge divided by its capacitance.
