AUTOOL PT640 GDI Fuel Pressure Gauge 0-360Bar Digital Measurement Pressure Gauge

The AUTOOL PT640 GDI Fuel Pressure Gauge is a digital fuel pressure tester for automotive GDI / direct injection fuel systems. It helps technicians measure high-pressure fuel pump and fuel injection system pressure with a wide 0-360bar range, clear 2.8-inch backlit display, multiple pressure unit switching, real-time pressure display, maximum / minimum pressure tracking, differential pressure display, data lock, clear, and zeroing functions. PT640 combines high-pressure digital measurement, unit switching, data holding, zeroing, and adapter support for GDI fuel pressure diagnosis. Review the confirmed PT640 measurement range, units, accuracy, resolution, battery requirement, operating temperature, overload pressure, and display functions before use. Before connecting the PT640 to a direct injection fuel line, release fuel pressure, install batteries, select the correct adapter, and take precautions against residual fuel leakage.
