BETOOLL 13pc Compression Tester with Spark Plug Tester – 0-300 PSI Engine Cylinder Gauge Kit

Overview

The BETOOLL 13pc Compression Tester with Spark Plug Tester combines a compact pressure gauge with dual spark plug testers to help you assess petrol engine cylinders and quickly spot potential issues. This versatile kit is designed for DIY enthusiasts and professionals who want a practical, field-ready diagnostic tool. It is intended for petrol engines and is not applicable to crude oil engines.

With a clear, triple-range gauge and a user-friendly release valve, you can inflate and deflate with one hand, keeping the workflow smooth and efficient. The kit’s thoughtful design supports real-world use—from home garages to small shops—so you can move between projects without swapping tools.

Key Benefits and How It Helps

• Versatile assessment: Tests cylinder compression to help identify potential engine cylinder problems in petrol engines, aiding quicker diagnostics without disassembly.
• Dual spark plug testers: Two testers work with an indicator light to help diagnose ignition and fuel delivery system concerns on multiple components, including engines and outboard motors.
• Single-handed operation: The release valve design enables easy inflation and deflation, making on-the-spot checks more comfortable during inspections.
• Broad compatibility: Includes 10 adapters to fit a wide range of engine types—cars, ships, trucks, lawn mowers, ATVs, boats, and more.
• Clear, precise readings: Triple-range gauge covers 0-300 psi, 0-20 bar, and 0-21 kg/cm² for fast, accurate checks in one tool.

What’s Included

• 13-piece compression tester kit
• 2 spark plug testers
• Release valve for smooth inflation and deflation
• 10 adapter connectors
• Triple-range pressure gauge (0-300 psi / 0-20 bar / 0-21 kg/cm²)

Suggested Use Scenarios

Use this kit to gauge cylinder health, verify ignition components, and assess fuel delivery pathways. It’s well-suited for routine maintenance, troubleshooting common engine misfires, and evaluating performance across a variety of petrol-powered machines. While it helps you narrow down issues, it does not guarantee a fix, and results may vary based on engine condition and operating environment.

Usage Tips

• Match the adapter to the correct cylinder port before connecting.
• Monitor the gauge reading after a steady pump to ensure stability.
• Use the spark plug testers to confirm spark under typical operating conditions (indicator light glow indicates activity).
• Deflate using the release valve once testing is complete to prepare for the next check.
