A manometer is a measuring instrument used to determine the pressure of a fluid, such as air or water. It consists of a tube connected to an indicator device that displays the pressure on a graduated scale.
The manometer can have a needle that moves across the scale or a digital display. It is used in various applications, such as in industry, medicine, and automotive, to measure pressure in systems such as tires, pressure vessels, or air conditioning systems.
It allows for precise monitoring and control of pressure to ensure proper and safe operation.
