Five-Hole Comparison Test and High Testing Accuracy: The spark plug tester has five spark plug sockets (1 standard test hole, 4 additional test holes), allowing you to test five spark plugs simultaneously. By comparing the spark strength between old and new spark plugs, you can judge the performance and ignition strength of the spark plugs and replace any faulty ones in a timely manner. The tester can also simulate the engine's operation, restoring the authenticity of the car's rotation speed, saving time and improving efficiency, with more accurate data.

Frequency Adjustable from 200-9000rpm and Digital Display Screen: The spark plug tester has a wide range of operating frequency adjustment and is designed with a digital display screen. Using the RPM button on the operating panel, you can adjust the operating frequency within the range of 200-9000rpm, which is clearly displayed on the digital screen for precise control and more accurate measurement results. The higher the frequency setting, the stronger the spark strength.

Easy Operation and Plug-and-Play: The automotive spark plug tester is easy to operate. First, insert the new spark plug into the standard test hole, then insert the old spark plug into the remaining test holes. Next, insert the power adapter into the power connector and turn on the power switch. The corresponding indicator light of each test hole will light up, and you can adjust the working frequency to compare and observe the performance of the spark plugs. (Note: the package does not include spark plugs.)

Widely Used in 12V Gasoline Vehicles: The spark tester is widely applicable and can be used to test spark plugs for 12V gasoline vehicles, suitable for 14mm and 16mm spark plugs. It is compatible with all spark plug tests for crankshaft engines and motorcycles on the market.

Important Tips: To ensure a correct purchase, please read the tester information carefully before placing an order. Do not pull out or insert the spark plug with the power supply connected. If you need to insert or remove a spark plug, please turn off the power first. When the spark plug is running, the voltage can reach tens of thousands of volts, so do not touch it directly with your bare hands.
