Voltage:

115V, 50/60 Hz
230V, 50/60 Hz
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.



Possible experiment topics:


  • 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)
