A vacuum gauge is used in a variety of applications. Vacuum gauges are available in a variety of shapes and sizes. A vacuum gauge will assist in measuring pressure. The pressure measured by a hoover gauge is the pressure in the real hoover. The pressure in a vacuum can differ from the pressure in the atmosphere. A hoover gauge can be both digital and dial. Vacuum gauges are utilised in a range of mechanical applications such as air pumps and compressors. Mechanics and contractors are common users of hoover gauges.
