Measurement / Control Unit ? Franck Hertz Experiment (115 V 50/60 Hz)

Product Overview

Measurement and control unit of the Franck Hertz experiment:?.. The quantization of energy as well as the generation registration and analysis of spectra and the associated experimental confirmation of models are important components of most curricula around the world. The well known 1913 experiment by James Franck and Gustav Hertz is fundamental to the detection of discrete energy states in atoms. Because of the importance of these findings into modern physics 3B Scientific offers three complete experiments compiled for school and university education (see Recommendation ). Product Information:?.. The Franck Hertz control unit can be used to operate the mercury filled Franck Hertz tube the neon filled Franck Hertz tube or the critical potential tubes S. It provides all the voltages needed to power the tubes and includes a highly sensitive built in DC amplifier for measuring collector current.?The voltages can simultaneously be read off a display. The accelerating voltage can be selected either as a manually adjusted stabilized DC voltage or as a sawtooth voltage (50 Hz). Additional measuring inputs are also available for the anode current and accelerating voltage. Specifications:?.. Mains voltage:?.. 115 V ?10% (50/60 Hz)?..
