A method for measuring the degree of vacuum below atmospheric pressure precision vacuum gauge. Precision vacuum gauge vacuum gauge is mainly used for general check or direct measurement of the degree of vacuum medium. Precision vacuum table can also be used to check for other vacuum measurement instrumentation, and with a certain degree of vacuum was a function of the parameters of other class instrumentation, test or calibration. Precision vacuum gauge accuracy levels are: 0.4; 0.25; 0.16. Measuring range precision vacuum table is divided into: -0.1 ~ 0MPa; -0.06 ~ 0MPa; -0.04 ~ 0MPa ;. Precision vacuum table with different installation structure type, such as radial band edge precision vacuum gauge, axial band edge precision vacuum table and so on.
