Pointer ElectroscopeInspect whether the conductor is live and whether the conductor is chargedWorking PrincipleWhen measuring the potential difference between two charged bodies, connect the electroscope metal casing to one charged body, connect the metal rod to another charged body, and generally ground the casing.If the earth potential is taken as zero, the potential of each charged body can be measured with an electroscope.When testing the electrification of the object, the electroscope ball can be used to the object under test first, and then the obtained electric charge is transferred to the electroscope metal rod, or the metal rod is directly contacted with the object.The easiest way to test the insulation of an object, as long as the object is grounded (touch it with your hands), the other point of the object is in with the charged electroscope metal rod, and the electroscope pointer is observed. If the pointer quickly returns to zero, The tested object is a conductor, otherwise it is an insulator.Product name: pointer electroscopeProduct size: 102*70*335mm/4.01*2.75*13.18 inProduct weight: 650gMaterial: plastic base, metal cylinder, frosted glassPurpose: This instrument is used for electrostatic experiment, can measure the potential difference between two charged objects; check whether the object is charged; check the object's insulation is negative, and perform the test of induction electrification, etc.

• *This instrument is used for static electricity experiments. It can measure the potential difference between two charged objects; check whether the object is charged; check whether the object is negative, check the insulation of the object, and perform inductive electrification tests.
• *When measuring the potential difference between two charged bodies, connect the metal shell of the electroscope to one charged body, connect the metal rod to the other charged body, and generally ground the shell. If the earth's electric potential is zero, the electric potential of each charged body can be measured with an electroscope.
• *When checking the charge of the object, the electroscope ball can be used to first the object to be inspected, and then transfer the obtained electric charge to the electroscope metal rod, or the metal rod can be directly contacted with the object.
• *The easiest way to check the insulation of an object is to ground the object (touch it with your hands), and another point of the object is inwith the charged electroscope metal rod. Observe the pointer of the electroscope. If the pointer returns to zero soon, The tested object is a conductor, otherwise it is an insulator.
• *It is best to wipe the insulating sleeve with a soft dry cloth before use, because dust and moisture are often affected, which can damage the insulation performance. When the instrument is severely affected by moisture, it is best to use it after drying.
