• Accurate Digital Diagnostics: This digital cylinder pressure gauge delivers precise engine compression readings from 3 to 300 PSI, helping you quickly identify issues like worn piston rings, cracked cylinder heads, faulty valves, or blown head gaskets in gasoline engines of cars, motorcycles, and trucks.
• Multi-Unit LCD Display: The intuitive digital display features four switchable pressure units—PSI, KPa, Bar, and Kgf/cm²—so you can read results in your preferred measurement. The clear LCD screen ensures easy interpretation even in low-light conditions, powered by standard AAA batteries (not included).
• Universal Vehicle Compatibility: Designed for all gasoline-powered vehicles including sedans, SUVs, motorcycles, and light trucks, this compression tester kit works seamlessly with fuel-injected engines. It’s an essential tool for DIY mechanics and professional technicians diagnosing engine performance problems.
• Premium Sealing & Leak Detection: Equipped with a high-quality rubber tube and precision adapters, the gauge maintains excellent air-tight sealing during testing, allowing accurate detection of cylinder leakage and pinpointing whether the issue stems from valves, piston rings, or head gaskets.
• Complete Adapter Set Included: The kit includes one digital gauge, one flexible rubber hose, and four plug thread adapters (14mm, 18mm, M10x1.0, M12x1.25, M14x1.25, M18x1.5) to fit most common engine types, ensuring you’re ready to test right out of the box without needing extra accessories.
