MOUMOUTEN Foil Electroscope Physics Electrometer, Foil Electroscope Demonstrator with Protractor, High Sensitivity Foil Electroscope Teaching Tools for Electrostatic Experiment and Education

• Electrostatic Experiment: This foil electroscope is suitable for electrostatic experiment, to check whether the object is charged and whether the charge of the object is positive or negative. It can also show the principle of charge conservation and charge distribution.
• Hands on Learning: This physics electrometer is perfect for a hands on classroom experience, mainly used for electrostatic experiments in middle school physics teaching. It can help students understand the nature and properties of electric charges and electric fields.
• Designed with Protractor: This foil electroscope demonstrator is designed with protractor, which can be used as a pointer electroscope, convenient for teaching and demonstration. The angle of the foil leaf can indicate the amount and polarity of the charge on the electroscope.
• High Sensitivity: These foil electroscope teaching tools feature high sensitivity, easily test the insulation of objects and demonstrate induction charging, etc. The foil leaf is made of thin metal, which can respond to very weak electric forces and show the effect of electrostatic induction.
• Compact Structure: This foil electrometer has light weight and compact structure, stable performance, easy to operate and carry. It is made of durable plastic and metal materials, which can withstand repeated use and ensure long service life.
