vacuum gauge
Measures negative pressure
A vacuum gauge measures pressure below atmospheric level—the degree of vacuum in a sealed system.
Mechanics use vacuum gauges to diagnose engine problems, while scientists and industrial operators monitor vacuum chambers and pumps.
The gauge typically displays readings in inches of mercury or millibars: The vacuum gauge showed a steady 20 inches.
