Electrometer (230 V, 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.

Please check the recommended and required tabs for additional supplies.

Aplications:

• Measurement of charge and voltage in electrostatics
