Cheap electroscope, Buy Directly from China Suppliers:Telescopic Acoustic-optic High Voltage Electric Electroscope 10KV Yellow
Product Name High Voltage Electroscope Material Plastic, Rubber, Metal Voltage 10KV Battery Power 4 x AB13 4.5V(not included here) Section 5 Tip Size (Approx.) 6.5mm / 0.26" Closed Size 36 x 385mm / 1.4" x 15.2" (D * L ) Extended Length 1120mm / 44.1" Handle Color Yellow Package Content 1 x High and Low Voltage ElectroscopeDescription: 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. 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.
