• Digital Accuracy with Switchable Units: This digital cylinder pressure gauge features an intuitive LCD display with four switchable pressure units (PSI, KPa, Bar, Kgf/cm²), allowing you to quickly and accurately read engine compression data without manual conversion. The clear digital readout ensures precise diagnostics for both professionals and DIY mechanics working on gasoline-powered vehicles.
• Comprehensive Engine Fault Detection: The engine compression tester kit helps identify common issues such as worn piston rings, cracked cylinder heads, faulty valves, or blown head gaskets by measuring cylinder leakage and pressure loss. With this digital cylinder pressure gauge, you can pinpoint the exact source of engine misfires or poor performance before costly damage occurs.
• Universal Compatibility for Multiple Vehicles: Designed for a wide range of applications, this compression tester works seamlessly with cars, motorcycles, trucks, and other gasoline engines equipped with spark plugs. Thanks to the included four thread adapters (M10x1.0, M12x1.25, M14x1.25, M18x1.5) and two spark plug connectors, the digital cylinder pressure gauge fits most standard engine types for versatile home or shop use.
• Durable Construction with Reliable Sealing: Built with a high-quality rubber hose and precision-machined metal adapters, this engine compression tester ensures excellent air-tight sealing during pressure tests, minimizing data errors. The robust materials withstand repeated use in demanding environments, while the compact design makes storage and transport easy for mobile technicians or garage enthusiasts.
• Complete Diagnostic Kit Ready to Use: The package includes 1 digital display gauge, 1 flexible rubber tube, 2 spark plug connectors (14mm and 18mm), and 4 metric thread adapters—everything needed to start testing right away. Powered by two AAA batteries (not included), the digital cylinder pressure gauge delivers low power consumption and long-lasting operation for reliable engine diagnostics anytime.
