Power Supply Unit for Franck-Hertz Experiment (230 V, 50/60 Hz)
Franck-Hertz Experiment

The quantization of energy and the generation, recording and evaluation of spectra, along with the experimental verification thereof, is included in most of the curricula used around the world. The well-known experiment first performed by Franck and Hertz in 1913 is critically important in terms of demonstrating discrete energy states in atoms.

Power Supply Unit for Franck-Hertz Experiment
Power supply unit for operating the mercury-filled Franck-Hertz tube U8482150 and the neon-filled Franck-Hertz tube U8482220. The equipment provides all the voltages needed to power the tubes and includes a sensitive built-in DC amplifier for measuring collector current.
The accelerating voltage can be provided manually or by means of a saw-tooth output voltage from the power supply unit. Additional measuring inputs are also available for the anode current and accelerating voltage.
