J2558 Frank - Hertz Experimental Instrument

frank - Hertz experimental device used to verify Bohr atomic level theory.can directly observe in the oscilloscope screen .

This instrument adopts the argon gas filling pipe as F - H pipe, can do experiment in the normal temperature,  do not need to heating and heat preservation, spectrum peak curve can be made of spot measurement method , also can be directly observe in the oscilloscope screen .
