Professional Compression Tester Kit, 300 PSI Triple-Scale Pressure Gauge, 13-Piece Engine Compression Test Set with 2 Spark Plug Testers for Cars, Trucks, ATVs & Small Gas Engines

• High-Definition, Three-Scale Dial: Equipped with a high-definition pressure gauge that supports three measurement scales—0–300 PSI, 0–20 Bar, and 0–21 kg/cm²—it offers high measurement accuracy, allowing you to read test data precisely anytime, anywhere.
• 13-Piece Professional Testing Kit: The complete set includes M10–M18 high-strength metal connectors, 2 spark plug test connectors, an extended test hose, and a storage and protective case. With a comprehensive range of accessories and broad compatibility, it meets the comprehensive diagnostic needs of various engines, ensuring convenient and efficient testing.
• Built-in Schrader Valve for More Stable Readings: The pressure gauge features a built-in, integrated Schrader valve, eliminating the need for an additional adapter valve to connect the hose to the fitting. This significantly enhances testing stability, effectively prevents data deviations, and ensures more accurate and reliable pressure test results.
• Quick Pressure Relief Safety Feature: Equipped with a professional quick-release safety valve that supports one-handed, one-button pressure relief, allowing for quick and safe pressure release after testing is complete. It eliminates safety hazards such as sudden pressure surges, is simple and effortless to operate, and ensures comprehensive testing safety.
• Precise Testing + Dedicated Compatibility Range: It can accurately capture peak engine pressure data, effectively detect internal engine issues such as piston ring wear and valve malfunctions, and provide a professional assessment of engine operating conditions. Compatible only with gasoline engines, including passenger cars, trucks, ATVs, and small gasoline-powered equipment; not suitable for diesel engines or crude oil engines.
