How is a vacuum measured
Web21 dec. 2024 · The first way to measure Hg is known as the Hg gauge (HgV). The scale goes from 0" Hg (atmospheric pressure) to 29.92" Hg (perfect vacuum). The second way to measure Hg is the Hg absolute (HgA). This measurement is the reverse of the Hg gauge. In this measurement, the gauge starts 29.92" Hg for atmospheric pressure, and 0" Hg is … WebMeasuring vacuum pressure is a fundamental element of all vacuum applications. Whether you are measuring pressures below 10 -10 mbar or higher pressures of 10 -2 mbar, all …
