The Autool PT640 is a digital fuel pressure tester specifically designed to measure pressure in GDI fuel systems (Gasoline Direct Injection). This instrument features a wide measurement range from 0–360 bar (0–5221.3 psi / 0–367 kg/cm²) — essential for the high pressures found in modern direct-injection petrol engines.
The PT640 features an illuminated 2.8-inch LCD display that clearly shows current, maximum, minimum and differential pressure readings. Easily switch between bar, psi and kg/cm². Additional features such as data hold and interface lock support stable and accurate measurements. The complete system comes in a sturdy carrying case.
