Dual Hole Spark Plug Tester: A Comprehensive Solution

Dual Plug Testing Capability: This spark plug tester features two plug sockets, allowing you to test and compare the performance of two spark plugs simultaneously. By observing the spark intensity, you can easily identify any underperforming or faulty plugs, enabling you to make informed replacement decisions.

Wide Testing Frequency Range: The engine ignition coil tester supports a testing frequency range of 0-6000 rpm, closely mirroring the actual working conditions of the engine. The higher the frequency, the more intense the spark, providing you with a clear visual representation of each plug's ignition performance. This feature is particularly beneficial in dimly lit environments, where the sparks can be observed more distinctly. However, it is not recommended to use this tester in bright surroundings, as the sparks may be less visible.

Universal Compatibility and Ease of Use: This automotive ignition tester is designed to be compatible with a wide range of 12V gasoline-powered vehicles, including both crankshaft engines and motorcycles. The user-friendly operation involves simply inserting the spark plugs into the test sockets and rotating the frequency knob to observe their performance at different RPM levels. Even without extensive automotive maintenance expertise, you can effectively test your spark plugs at home.

Versatile Spark Plug Compatibility: This spark plug tester accommodates a wide range of plug diameters, up to a maximum of 13mm. If the plug diameter is exactly 13mm, it will fit snugly into the tester's aperture. For plugs smaller than 13mm, a slight gap may be present, but this will not affect the testing process. However, for a more secure fit, the addition of two limit washers can provide increased stability.

Adapting to Varying Plug Lengths: (a) For longer spark plugs, you can place shims on the sockets before inserting the plug to ensure a firm connection, with the negative power supply connected to the socket. (b) For shorter spark plugs, such as those found in lawn mowers, chainsaws, or small engines, the inability to be clamped by the base clamp is not a concern. As long as the plug can make contact with the metal clamp, the positive power supply can be connected, and the negative power supply can be connected through the socket. The plug may be slightly tilted, but this does not impact the testing. (c) The base clamp provides the positive power supply, while the socket supplies the negative power supply.
