[Dual-hole test]: Automotive spark plug tester by simulating the engine working for dual-hole test, while comparing the spark strength of the two spark race, rapid confirmation of defective spark plugs, improve efficiency and time
[Plug and play] :Insert the spark plug into the test hole, close the cover, plug in the power supply, adjust the frequency, you can start to use, equipped with indicators, you can intuitively observe the status of the spark tester.
[Adjustable Frequency]: The working frequency of the ignition tester is 0-6000 rpm, the frequency can be adjusted by turning the knob, the higher the frequency, the stronger the spark intensity.
[Wide and durable]: This spark plug tester is suitable for most 12V gasoline engine spark plugs (12mm diameter). Made of durable ABS material with impact and heat resistance.
[Note]: Avoid testing lawnmowers, chainsaws and most small engines. Use in low light conditions to effectively improve the accuracy of test results
