Engine Compression Test Set, 13‑Piece Compression Tester Kit with 300 PSI Triple‑Scale Pressure Gauge & 2 Spark Plug Testers for Car Truck ATV Small Gas Engines (Black)

Professional Compression Tester Kit with Fluorescent

• High-Definition Triple-Scale Dial for Accurate Readings: This compression tester features a high-definition precision pressure gauge with three common measurement units: 0–300 PSI, 0–20 Bar, and 0–21 kg/cm². Boasting high measurement accuracy and clear data display, it allows you to acquire precise engine pressure data in real time.
• 13-Piece Complete Tool Kit with Wide Compatibility: This all-in-one testing set includes M10–M18 high-strength metal connectors, 2 spark plug test connectors, an extended test hose, and a durable storage case. It comes with full accessories for direct use without extra purchases.
• Built-in Schrader Valve for Stable & Reliable Data: Built with an integrated Schrader valve, this pressure gauge needs no extra adapter valves to connect hoses and fittings. The optimized integrated structure greatly improves overall testing stability. It prevents data fluctuation and deviation during operation, effectively avoiding test errors and ensuring every pressure test result is accurate and consistent.
• One-Button Quick Pressure Relief for Safe Operation: Equipped with a premium quick-release safety valve, this tester supports simple one-handed, one-button pressure relief after testing. It rapidly and safely releases residual internal pressure and avoids safety risks from sudden pressure surges.
• Precise Engine Diagnosis for Gasoline-Powered Equipment: This tester accurately captures engine peak pressure data to diagnose internal issues such as piston ring wear and valve malfunctions, helping you professionally evaluate engine working conditions. It fits most gasoline engines on cars, trucks, ATVs, and small gasoline-powered equipment. Note: It is not applicable to diesel engines or crude oil engines.
