How Many Microns is a Good Vacuum? Tips for Achieving Optimal Vacuum Levels
A good vacuum is typically measured by its level of vacuum pressure, which is expressed in microns. The lower the number of microns, the greater the vacuum. A vacuum with a level of 500 microns or less is considered good for general purposes, while a more precise vacuum with a level of 10 microns or less is necessary for specific applications such as semiconductor manufacturing or aerospace technology.
