Spark Plug Tester Dual Holes, 0 To 6000rpm Adjustable Working Frequency Automotive Engine Ignition Coil Tester For 12V Gasoline Vehicles And Motorcycles

Product details

• NOTE 1: If the spark plug cannot reach the negative cylinder iron, use a shim for testing. It is only necessary to use it if the negative cylinder iron cannot be contacted, not for every test. [*Spark plugs that do not require shims will cause normal spark plugs to not work if used.].
• 0~6000rpm Adjustable Working Frequency: The spark plug tester can truly simulate the working conditions of the engine and can detect the ignition of the spark plug under different working conditions, with a range of up to 0 to 6000rpm/min. You can adjust it according based on your needs by rotating the switch. The higher the set frequency, the stronger the spark intensity..
• Dual Holes Automotive Spark Plug Tester: The spark plug tester has two test holes, which can test and compare brand new spark plugs and spark plugs to be tested at the same time. By comparing the spark intensities of the two spark plugs,judge the performance and ignition intensity of the spark plugs,and replace the broken spark plugs in time..
• Plug and Play: Just put the spark plug into the test hole, connect the power supply and adjust the working frequency to start the test. It also has a power indicator light and two high-voltage signal indicators, which can help you observe the test situation more intuitively..
• NOTE 2: It is not suitable for testing short plugs on lawn mowers, chainsaws, or most small motors. Please do not touch the spark plug during the test to prevent the risk of electric shock. Spark Plug Not Included.
• Widely Application: Our car spark plug tester is made of high-quality thermoplastic polymer structural material with good heat resistance and impact resistance to prolong its service life. Widely used for testing 12V gasoline vehicles with a diameter of 12mm. Universal for spark plug tests crankshaft engines and motorcycles..
