The Coulomb Meter provides a means of exploring and understanding static electricity and charge. It is a useful tool for electrostatic experiments and behaves similar to that of a digital electroscope. The display will show the number of coulombs deposited into the instrument either by current through a resistance, from a capacitor, or from a source of static electricity. The Coulomb meter has a capacitor connecting the positive and negative banana clip sockets. In parallel with the capacitor is a digital voltmeter. When a material is rubbed against the electrode, the capacitor is charged and the voltmeter measures the voltage across the capacitor. An internal circuit calculates the charge based on the measured voltage. An electroscope will deflect its vane, however, this instrument shows the charge digitally in Coulombs up to 1999 nC. Accuracy +/- 10 nC. Has a maximum voltage of 100V.
