Hey Folks,
I am looking to buy a vacuum pump for a variety of HV experiments,
crackle tubes, lightning tubes etc. I find measurements in three different
measures: In.Hg. ,Torr ,& mb. Does anyone have a good conversion table for
these measurements?? What would be a good low number to work towards when
buying a pump, short of buying the most expensive one I can afford???
Hope this is not too off-topic on this list...
Thanx
