Now I'm reading over the vacuum pumps but I'm really confused! Because it says:
The dial gauge is located in the top front section of the system.The dial vacuum gauge is commonly used to indicate vacuum level when operating in the rough vacuum range (2 torr, 2.7mbar, 29.8 in Hg).
Are these values the same???
And at the same pump its said that
Ultimate Pressure (Torr) (mbar) = 2(2,7)
Maximum Vacuum,in,Hg : 29,80
What do these mean???
