Experiment

Application Area:_..

•	Measurement of charge and voltage in electrostatics
•	Measurement of charge and voltage for a plate capacitor
•	Ionisation of air by burning gases or α radiation
•	Hallwachs effect (external photoelectric effect)

Product Information:_..

Impedance converter with high-resistance input for measuring extremely small charges and currents. The input signal is converted into a proportional voltage, which can then be measured with an external voltmeter. During the measurement the potentials of the electrometer and the experimenter must be matched by using a metal rod connected to earth.
Includes a 12-V AC plug-in power supply.

Please check the recommended and required tabs for additional supplies.
