| AUTOOL PT502 vacuum pressure gauge is specifically designed for detecting vacuum pressure-related faults in various automotive systems. With a measurement range of -101KPa to 0KPa and a measurement accuracy of ±1% FS, it can precisely measure vacuum pressure in key areas such as the engine intake manifold, crankcase, EGR valve, exhaust system, turbocharger, and air conditioning ventilation system. By monitoring pressure data, it can accurately pinpoint engine seal issues, pipeline leak points, and system blockages. | |
