In the automotive repair field, key components such as the engine intake manifold, exhaust system, and exhaust gas recirculation (EGR) valve all rely on stable vacuum pressure for proper operation. When these vacuum systems experience leaks or abnormal pressure, it can lead to issues such as unstable engine idle, increased fuel consumption, and a hard brake pedal. These issues are often highly concealed, making it difficult for technicians to accurately locate the problem using only visual observation or basic tools. This not only increases the risk of misdiagnosis and ineffective disassembly but also raises repair costs.
The AUTOOL PT502 is a diagnostic tool 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. The built-in temperature sensor features intelligent temperature compensation, which can real-time correct deviations in pressure measurements caused by ambient temperature changes, effectively assisting maintenance technicians in locating concealed issues and improving diagnostic accuracy and maintenance efficiency.
AUTOOL PT502 Vacuum Pressure Gauge Features
High-precision Sensor
The built-in high-precision pressure sensor can quickly and sensitively detect pressure changes and provide real-time measurement results. It features a measurement range of -101KPa to 0KPa and maintains a measurement accuracy of ±1% FS across the entire working range, effectively ensuring the reliability and efficiency of vacuum pressure testing.
Smart Temperature Compensation
The built-in temperature sensor with temperature compensation can monitor ambient temperature changes in real-time and automatically correct measurement deviations, ensuring stable and reliable measurement accuracy in working environments ranging from -10°C to 60°C.
Direct Vehicle Power Supply
It can be directly connected to the vehicle’s 12V power supply, providing worry-free power. With enhanced battery life and a 40% increase in power stability, it ensures a reliable and continuous power supply.
Reverse Polarity Protection
Equipped with reverse polarity protection, the device automatically cuts off the current if the power supply’s positive and negative terminals are accidentally reversed, effectively safeguarding both the vacuum pressure gauge and the battery.
Multiple Application Scenarios
Professionally designed for the automotive repair field, it is suitable for vacuum pressure testing in key systems such as the intake manifold, exhaust system, crankcase ventilation system, and exhaust gas valve.
Specifications
Packing List
The AUTOOL PT502 vacuum pressure gauge is equipped with a high-precision pressure sensor and intelligent temperature compensation, providing accurate and reliable vacuum pressure testing results. Independently developed by AUTOOL, it has a number of intellectual property rights, as well as the authoritative certification of CE, FCC, ROHS and other testing organizations. Compared to the traditional mechanical vacuum gauge with needle readings, the PT502 is equipped with a digital display that shows real-time vacuum measurements. By providing precise pressure data, it allows for a quick assessment of engine seal integrity and accurate identification of leak points and exhaust system blockages. It also effectively helps diagnose common faults such as piston ring sticking and poor valve sealing, making it an ideal diagnostic tool for modern repair workshops.
