Product Information:

The Franck-Hertz measurement / control unit can be used to operate the Franck-Hertz tube with mercury filling, the neon-gas filled Franck-Hertz tube, or the electron tube – ionization potentials.
It provides all the voltages required to operate the tubes and includes a highly sensitive built-in DC amplifier for measuring the collector current. The voltages can be read simultaneously on a single display. Additional analog measurement outputs are provided for the anode current and accelerating voltage. The accelerating voltage can be selected either as a manually adjustable, stabilized DC voltage or as a sawtooth voltage (50 Hz).
