The barometer is filled with Mercury and vacuumed within. A barometer is an instrument that is used to measure atmospheric pressure. The atm unit is used to measure atmospheric pressure. P gauge is negative pressure What is Atmospheric Pressure?Īir is present above sea level, and there are so many layers that the higher you go, the more pressure air exerts, and atmospheric pressure is the pressure exerted by air in the atmosphere. A measurement of pressure below atmospheric pressure is known as negative pressure or vacuum pressure. The pressure measured in proportion to absolute zero pressure in a vacuum is known as absolute pressure. It is equal to measuring pressure plus ambient pressure and is measured with a barometer. P abs is the abbreviation for absolute pressure.
