Telescopic High Voltage Acoustic-optic Electroscope Electric Tester 35KV (1e10038ba46eda3b072609f4ce6463d2)

Aexit Telescopic High Voltage Acoustic-optic Electroscope Electric Tester 35KV (1e10038ba46eda3b072609f4ce6463d2)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.00Description in FrenchAppareil de contrôle électrique 35KV d'électroscope électro-acoustique haute télescopiqueNom du produit: Électroscope haute ; Matériel: plastique, caoutchouc, métal; : 35KVPuissance de la batterie: 4 x AB13 4.5V (non inclus ici); Section: 5Taille de la pointe (environ): 6,5 mm / 0,26' '; Taille fermée: 36 x 385 mm / 1,4' 'x 15,2' '(D * L)Longueur étendue: 1120mm / 44.1' '; Couleur: JaunePoids: 495g; Contenu du coffret: 1 x électroscope haute basse
