Product Details
✓Dual spark plug comparison for faster troubleshooting – Compare two compatible spark plugs side by side at the same test setting; ANCEL SP02 makes differences in visible spark strength and consistency easier to spot, reducing repeated plug swapping and helping you check suspect plugs more efficiently
✓Reduce guesswork before replacing plugs – Investigating misfires, hard starting or rough idle? Check spark activity before buying replacement plugs; SP02 provides an additional inspection step to help identify plugs that need further attention and guide your next troubleshooting decision
✓Adjustable RPM simulation for flexible testing – Turn the built-in control knob to adjust firing frequency through a simulated range of 0–6000 RPM; observe spark continuity at different settings and look for weak or intermittent sparking during garage or workshop checks
✓Compatibility for 12V gasoline engine applications – Tests compatible spark plugs used in cars, motorcycles, ATVs, lawn equipment, generators and small marine engines with 12V electrical systems; supports spark plugs with a length of 33–43 mm and an insulator diameter under 12.2 mm; confirm plug dimensions and fit before purchase
✓Included power adapter for convenient setup – Connect SP02 to a wall outlet using the supplied power adapter; the adapter accepts 100–240V AC and converts it to 12V 1A DC to power the tester, making setup straightforward for garage and workshop spark plug checks
✓Compact design with a protective viewing cover – A transparent protective cover allows clear observation of spark activity while helping reduce accidental contact with the test area; the compact, lightweight housing is easy to store and convenient for routine checks in home garages and professional workshops
✓Compatibility notice (important before purchase) – This spark plug tester may not fit plugs outside the specified size range or certain specialized ignition systems. Compatibility varies by engine design and plug type. Please confirm dimensions before use to ensure accurate testing results and safe operation(Contact toptool_services@outlook.com)
