product manual:

       Vacuum pressure gauges are based on atmospheric pressure and are used to measure instruments that are less than atmospheric pressure. The vacuum pressure gauge is suitable for measuring the vacuum pressure of liquids and gases that have no explosion, no crystallization, and no solidification, and have no corrosive effect on copper and copper alloys.

       application:

       Widely used in gas transportation, measuring the pressure of various liquids, gases, steam and other media that are non-corrosive, non-explosive, crystalline, and non-solidified in pipeline liquids and closed containers, such as various industrial automatic control environments, involving petroleum Pipeline, water conservancy and hydropower, railway transportation, intelligent building, production control, aerospace, military industry, petrochemical, oil well, power, ship, machine tool, pipeline air supply, vacuum equipment and many other industries.

       Features:

       (1) Stable performance, high measurement accuracy, and fast response speed.

       (2) Accuracy above 0.5 can be used as a standard vacuum.

       (3) The total pressure is measured, including the pressure of gas and steam.

       (4) The measurement result has nothing to do with the type, composition and nature of the gas.

       (5) In the process of measuring m, the vacuum gauge itself has little inhalation and outgassing, which will not affect the measured atmosphere.

       (6) There are no high-temperature parts inside the vacuum gauge, which will not decompose oil vapor.

       (7) If corrosion-resistant materials are used, the pressure of corrosive gas can be measured.

       (8) The structure is firm and easy to seal and install.

       (9) The operation is simple and does not need to be adjusted, but it needs regular verification.
