However, it measures the vacuum based on ionization of the residual gas, not on thermal conductivity. For latter kind see Pirani gauge. The ionization and thermal conductivity gauges are totally different in operating principle, construction, and range of operation. Nice photo and nice gauge.

I was fiddling with old High-Frequency gear when i was a kid and tubes always fascinated me (and they still do). I look forward to more tube stills ;) I really like this series of tubes and ancient electronic circuitry.
