• High Durability​: With metal connectors and advanced manufacturing techniques, the internal circuitry is expertly engineered to endure repeated usage and diverse challenging conditions. Its long service life ensures users receive stable and reliable testing, ultimately lowering overall usage costs.
• ​Easy to Read​: The tester’s viewing window clearly shows white lettering on the scale, making measurements at 10k, 20k, 30k, and 40k ohms easy to read. This high-visibility design improves both ease of operation and accuracy during use.
• ​Rapid Detection​: This tool quickly measures essential spark plug parameters such as ignition voltage and ignition energy. It accurately determines whether spark plugs ignite properly and evaluates ignition performance, helping users promptly identify potential ignition issues and effectively prevent misfires and burnt ignition coils.
• ​Easy to Operate​: Included with the ignition coil tester are a rubber-coated grounding wire, a grounding alligator clip, and a spring for safe, stable high-voltage current transmission. Attach the alligator clip to the engine, connect the other end to the spark plug wire, and observe the spark length through the small viewing window—longer spark gaps indicate stronger ignition coils.
• ​Good Compatibility​: This tester is compatible with a wide variety of spark plug types and specifications, including those commonly used in cars, motorcycles, and small engines. Its broad applicability eliminates the need for multiple testers, reducing costs for users working with different spark plug models.
