Vacuum grease is one of the working media of vacuum equipment. Its important performance index is saturated vapor pressure. Zhang Zhongli and Wang Yong, two scholars from Lanzhou Institute of Physics, developed a microcomputer measurement and control system for automatic control and detection on the basis of LW-C1 vacuum oil saturated vapor pressure Tester. His paper "Automation of Vacuum Oil Saturated Vapor Pressure Test" introduced the specific development and test process, including working principle, microcomputer measurement and control system (microcomputer subsystem, balance subsystem, temperature control subsystem), improvement of experimental methods, use effect, test result.
