The Car Spark Plug Tester is one of DUOYI's popular offerings. It is a dual-hole spark tester designed for 12V gasoline vehicles, allowing users to test and compare the performance and ignition strength of spark plugs.

To use the tester, simply place the spark plug to be tested into one of the two test holes. If comparing a new and an old spark plug, the new one can be placed in hole 1 and the old one in hole 2. Close the protective cover, plug in the adapter, and connect the tester to a power source.

Turn the key switch clockwise to power on the tester, with the indicator light turning green. Continue turning the switch to adjust the working frequency, which can be set between 500-6000 rpm. The higher the frequency, the stronger the spark produced, allowing for a comprehensive assessment of the spark plug's performance.

The tester is compatible with 12V gasoline vehicle spark plugs, including both 14mm and 16mm sizes. It is not suitable for use with lawn mowers or chainsaws. The package includes the tester, a power adapter, and a user manual.
