Spark Plug Tester for 12V Gasoline Vehicles and Motorcycles

The Dual Holes Automotive Spark Plug Tester is designed to facilitate the testing and comparison of brand new and used spark plugs simultaneously. By comparing the spark intensities of the two spark plugs, users can effectively judge the performance and ignition intensity of the spark plugs, enabling timely replacement of any faulty ones.

Featuring an Adjustable Working Frequency range of 0 to 6000 rpm/min, this spark plug tester can accurately simulate the actual working conditions of the engine, allowing for the detection of the ignition performance of spark plugs under various operating scenarios. Users can simply rotate the switch to adjust the frequency as per their requirements, with the higher the set frequency, the stronger the resulting spark intensity.

Constructed with high-quality thermoplastic polymer structural material, the spark plug tester boasts exceptional heat resistance and impact resistance, ensuring its prolonged service life. Designed for widespread compatibility, the tester is suitable for testing 12V gasoline vehicles with a 12mm spark plug diameter, making it a versatile tool for testing crankshaft engines and motorcycles.

The user-friendly "Plug and Play" design of the tester simplifies the testing process. Users need only insert the spark plug into the test hole, connect the power supply, and adjust the working frequency to initiate the test. The tester is also equipped with a power indicator light and two high-voltage signal indicators, allowing for more intuitive observation of the test results.

To further enhance the customer experience, the spark plug tester comes with a 100% no-questions-asked return policy and a 24-month warranty. Should users encounter any issues with the tester, they can reach out to the manufacturer's professional technical team via Amazon, who will strive to resolve the problems within 24 hours.

It is important to note that this spark plug tester is not suitable for testing short plugs on lawn mowers, chainsaws, or most small motors. Additionally, users should refrain from touching the spark plug during the test to prevent the risk of electric shock. It is worth mentioning that the spark plug itself is not included with the tester.
