The probe is placed against the neck of the tube, and if the tube is gassy, the neck of the tube will fluoresce. No fluorescence=good vacuum

Crude, but for crt quality purposes, it is good enough.

This is what it looks like

Thanks, I was curious about how it was used in this case. That makes sense.

I actually have one that I saved from being tossed many years ago. I stuck in a piece of bus bar wire to replace the missing probe.
