Working Principle: The automotive spark plug tester operates on the principle of simulating the actual engine's work to evaluate the spark plug's performance and ignition strength. This tester is designed to test spark plugs (12 mm diameter) for 12V gasoline vehicles, motorcycles, lawn mowers, garden tractors, scooters, snow blowers, and boats.

Dual Hole Test and Time Saving: Two spark plugs can be tested simultaneously. Insert the new spark plug and the spark plug to be tested into the spark plug socket. By comparing the working performance of the two spark plugs, you can determine if the spark plugs need replacement.

Adjustable Operating Frequency: The operating frequency range is 0-6000 rpm, and the frequency can be adjusted by turning the button. The higher the frequency, the greater the energy output used to test the ignition performance of the spark plug.

Easy to Operate: First, plug the spark plug into the socket, then put on the safety cover, connect the power supply, and finally set the working frequency of the tester. (Note: For your safety, please unplug the spark plug after turning off the tester.)

ABS Transparent Safety Cover Design: The spark plug area is equipped with a protective cover to prevent accidents. The transparent protective cover also allows for visualization of test results. The variable RPM feature helps you identify exactly where your plugs are failing. The ABS material ensures durability and heat resistance. Do not open the cover until the test is complete.
