Air Manometer And Pressure Gauge

　　What is Air manometer?

　　A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Barometric pressure trends can predict short-term changes in weather. A large number of barometric measurements are used in surface weather analysis to help find surface valleys, high-pressure systems, and frontal boundaries.

　　What is a pressure gauge?

　　A pressure gauge is a device in which a suitable liquid column is used to measure the pressure difference between two points or between a point and the atmosphere.

　　Air manometer and pressure gauge

　　Air manometers and pressure gauges are used to measure pressure. They are simple tools based on the same principles. However, they are used in different situations. Today, there is much advanced equipment to replace the old Air manometer and pressure gauge, they are more user-friendly, fast, and reliable.

　　What is the difference between an air manometer and a pressure gauge?

　　An air manometer is a closed pressure gauge.

　　An air manometer is specially used to measure atmospheric pressure, and a pressure gauge can also be used to measure pressure below atmospheric pressure.

　　In the manometer, the two ends of the tube are open to the outside (some may have a closed-end), while in the Air manometer, the glass tube is sealed at one end, which contains the vacuum.

　　Air manometer is an instrument for measuring environmental pressure-the range is very limited, about 5%.

　　The pressure gauge is a standard pressure instrument suitable for any defined measuring range, which may be as high as 100 bar or higher.

　　the silicone-filled pressure gauge is also our product, welcome to consult and purchase.
