  • A Brief Discussion of Pressure and Vacuum Levels

    A vacuum gauge is used to measure the pressure in a vacuum—which is typically divided into two subcategories, high (i.e., hard) vacuum and low (i.e,, soft) vacuum. To select the right pressure device for a specific application requires one to know the desired pressure range and the capability of the pumping system to achieve the desired pressure.

  • Vacuum - Wikipedia

    The SI unit of pressure is the pascal (symbol Pa), but vacuum is often measured in torrs, named for an Italian physicist Torricelli (1608–1647). A torr is equal to the displacement of a millimeter of mercury (mmHg) in a manometer with 1 torr equaling 133.3223684 pascals above absolute zero pressure.
