Impedance converter with high-resistance input for measuring extremely small charges and currents.

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)
Electrometer gain factor of 1.00

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.

BodyTextAccessories: Set of accessories is available for carrying out basic experiments on electrostatics, electricity and the photoelectric effect. Set (in combination with the 3b American Scientific Electrometer) includes 1 Faraday cup; 1 pair of friction rods; 1 metal rod with 4 mm drilled hole; 1 safety adapted socket; 1 plug-in capacitor 1 nF; 1 plug-in capacitor 10 nF; 1 plug-in resistor 100 MΩ; 1 pug-in resistor 1 GΩ; 1 plug in resistor 10 GΩ; 1 zinc electrode; and 1 grid electrode. Electrometer is required, but sold separately.

Ordering information: Accessory set is sold separately.

Delivery: Includes a 12 VAC plug-in power supply.
