Can any one tell me how a vaccum pump can be specified. I want to buy a vaccum pump on which specification I can buy, to vaccum a refrigration system and in which unit I can Measure a vaccum in the system
Specify the "Linda Lovelace" brand, which can suck the chrome off a trailer hitch, down to about 1 torr or so. If you like working with antique lab glassware, use a McLeod gauge to measure this; or else an electronic vacuum gauge.
