Car Spark Plug Tester is for testing the performance and strength of spark plugs. The product simulates actual engine conditions and works up to 6000rpm. It is compatible with all spark plug tests for crankshaft engines and motorcycles on the market. It can also test two holes at the same time and is designed with a protective cover to ensure the safe operation of maintenance personnel during the test.
Car Spark Plug Tester
SPT101 automotive spark plug tester is mainly used to test the performance and strength of spark plugs to help you judge the quality of spark plugs. It can be used to test spark plugs of 12V gasoline vehicles and 99% of crankshaft engines and motorcycles on the market.
It can truly simulate the normal operation of the engine and help you judge the performance of the spark plug more accurately. Its working frequency can reach 6000rpm at most. It can also test two holes at the same time, and is designed with a protective cover, which is safer to use.
Car Spark Plug Test Principle
In automobile ignition system, the high-voltage ignition coil generates a high-voltage (10000 volts or more), and the spark plug diverts it form high -tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The Detector could tell the good spark plugs from the bad by the strength of the spark.

Car Spark Plug Tester Using Note:
The Spark Plug Tester is a high-voltage detector, so do not touch spark plug with hand at work to avoid danger.
Please Turn Off Power before you place spark plug.
In automobile ignition system, the high-voltage ignition coil generates a high-voltage, and the spark plug diverts it form high -tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture.
The Detector could tell the good spark plugs from the bad by the strength of the spark.
Up to 1000V voltage will be generated during test, Please close the protective cover before testing.
