Warning!

Do NOT leave the Franck-Hertz tube temperature above 200 C for extended periods of time! See the bottom of the first page of the tube manual:

"Ensure via control of the oven temperature (i.e. the oven voltage) that the maximum temperature limit for the Franck-Hertz tube is not exceeded (permanent operation 200 C, short-term peak value 220 C)."
