• 1.The spark plug injection port has been changed from 1.08cm to 1.78cm, and the structure has been segmented, allowing for a wider range of applications.

  •  2.The length, width, and height of the transparent cover have been changed from 5.6cm*6.6cm*5.1cm to 6.1cm*7cm*5.6cm.

  • 3.The mask has also been adjusted to follow the structural changes.

  •  4.The power has been upgraded with software, and during testing, the spark intensity was clearly 2-3 times higher than the previous model. The advantages of the new model are:
  • 4.1. It can test a wider range of spark plugs, suitable for testing spark plugs for cars, lawn mowers, motorcycles, and more. 
  • 4.2. The spark intensity is stronger during testing, making it easier to distinguish between new and old spark plugs, thus determining the quality of the spark plug.

【Dual Hole Testing & Protective Cover Protection】Spark plug tester has two spark plug socket,it can test two spark plugs (good spark plug & bad spark plug) 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.The design of the protective cover can prevent you from the risk of electric shock during the test,which effectively guarantees your safety during the operation.
 
 
【0~6000rpm Working Frequency Adjustable & More Accurate Data】The automotive tools has a wide adjustment range of working frequency.By operating the rotary switch,you can adjust the working frequency in the range of 0~6000rpm,the higher the set frequency,the stronger the spark intensity.Spark plug tester can also simulate the work of the engine,restore the authenticity of the car rotate speed,save time and high efficiency,and the data is more accurate,which can better test the spark plug.
 
【High-Quality ABS Material With Impact Resistance & Heat Resistance】Ignition tester is made of high-quality ABS material,which has the characteristics of impact resistance and heat resistance.It can provide you with long-term service and reduce the cost caused by frequent tool replacement.
【Plug And Play & Intuitively Display Spark Plug Status】Spark tester automotive is easy to operate, and you can start using it after connecting the adapter. The spark plug tester comes with a power supply/high voltage indicator light, which can help you observe the state of the spark plug more intuitively.

【Widely Used In 12V Gasoline Vehicles Car Spark Plugs】Spark tester is widely used, and can be used to test 12V gasoline vehicles car spark plugs, suitable for spark plugs within 12MM. Our products are only suitable for car spark plug detection (except Ford cars).
 
【Note】Spark plugs tester is a high voltage detector.Please do not touch the spark plug during the test to prevent the risk of electric shock.
