AUTOOL PT502 Vaccum Pressure Gauge

The AUTOOL PT502 is a digital vacuum pressure gauge designed for automotive negative-pressure diagnosis. With a measurement range of -101kPa to 0kPa and ±1%FS accuracy, it helps technicians measure vacuum pressure in key systems such as the engine intake manifold, crankcase, EGR / exhaust valve, exhaust system, turbocharger vacuum line, and A/C ventilation system. By monitoring pressure data, PT502 helps locate engine sealing problems, pipeline leaks, system blockages, and concealed vacuum-related faults more efficiently. PT502 combines a high-precision pressure sensor, smart temperature compensation, direct vehicle power, and reverse polarity protection for reliable vacuum-pressure diagnosis in automotive repair work. Use PT502 for negative-pressure diagnosis in key automotive systems where vacuum data helps reveal leaks, blockage, sealing failure, or abnormal pressure behavior. Confirm the measurement range, accuracy, voltage, current, temperature range, cable length, and negative-pressure-only limitation before use. PT502 is a negative-pressure-only diagnostic gauge. Review the zeroing and pressure-use limitations before testing. Key features • Vacuum Fault Diagnosis: Measures automotive vacuum pressure to help locate seal issues, leak points, and system blockages. • Wide Negative Range: The -101 kPa to 0 kPa range supports testing across multiple vacuum-related vehicle systems. • Temperature Compensation: A built-in temperature sensor helps correct pressure-reading deviation caused by ambient temperature changes. • Product: AUTOOL PT502 Vacuum Pressure Gauge • Pressure Type: Negative pressure only • Pressure Measurement: -101kPa to 0kPa
