• Accurate Digital Diagnostics: This 3-300 PSI digital cylinder pressure gauge delivers precise engine compression readings via a clear LCD display with four switchable units (PSI, KPa, Bar, Kgf/cm²), helping you quickly identify issues like worn piston rings, blown head gaskets, or cracked cylinder heads in gasoline engines.
• Universal Compatibility: The engine compression tester kit includes four spark plug adapters (14mm, 18mm) and four thread adapters (M10x1.0, M12x1.25, M14x1.25, M18x1.5), making it compatible with most cars, motorcycles, trucks, and other fuel-injected gasoline vehicles for reliable at-home or professional diagnostics.
• Practical for DIYers and Mechanics: Whether you’re a weekend car enthusiast or a seasoned technician, this cylinder pressure gauge helps pinpoint cylinder leakage sources, evaluate valve or ring wear, and verify engine health before major repairs—saving time and costly shop visits.
• Durable and User-Friendly Design: Built with a high-seal rubber tube and robust connectors, this compression tester ensures minimal air leakage during testing. The intuitive button layout lets you switch units or power on/off easily, while the low-battery indicator prevents inaccurate readings.
• Complete Ready-to-Use Kit: Each package includes 1 digital display gauge, 1 flexible rubber tube, 2 spark plug adapters (14mm and 18mm), and 4 metric thread adapters (M10 to M18), all powered by two replaceable AAA batteries (not included)—everything needed for immediate engine diagnostics.
