Ultimate Vacuum / Pressure:
|
|
Vacuum or pressure is often measured in torr, or mm Hg referenced above absolute zero pressure. Sometimes the following reference terms are used:
1 torr and above: Rough Vacuum
0.001 to 1.0 torr: Medium Vacuum
Below 0.001 torr: High Vacuum
There are other terms and standards used such as medium vacuum and ultra high vacuum; consult supplier for application specifications.
