Spark Plug Tester for 12V Gasoline Vehicles

The Dual Holes Spark Tester for 12V Gasoline Vehicles is a versatile ignition coil tester that operates at a working frequency of 500-6000 rpm, complete with a protective cover. Specification-wise, it is designed for use with 12V gasoline vehicle spark plugs, powered by a 100-240V AC to 12V 1A DC adapter.

The simulated engine speed range can be controlled between 500-6000 rpm, and the spark plug inner hole diameter accommodated is 12mm. Using this tester is straightforward - first, place the spark plug in the test hole, then cover the protective shield, connect the power supply, and adjust the working frequency. Through the transparent cover, you can observe the spark plug's test status.

A few important precautions to note: power should be turned off before inserting the spark plug, and the high-voltage nature of the tester means users should avoid directly touching the spark plug during operation to prevent any danger.

This Dual Holes Spark Tester is compatible with most 12V gasoline car spark plugs, though it is not suitable for lawn mowers or chainsaws. The transparent protective cover allows for clear visibility of the test data while safeguarding the user's safety during the testing process.

The 500-6000 rpm working frequency range provides flexibility, as higher frequency settings correspond to stronger spark intensity. The convenient rotary switch enables easy adjustment based on individual requirements.

The dual holes testing functionality permits a more thorough evaluation of the spark plug's performance - simply place both the new and the used spark plug in the respective test holes to make an accurate assessment efficiently and quickly.

The operation of this Dual Holes Spark Tester is exceptionally straightforward - just insert the spark plug, cover the shield, power on, and commence testing, without any complex steps. Additionally, the high-voltage indicator light makes it easy to observe the spark plug's test status.
