About this item

Product details

📢What is the role of the spark plug?

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber and generate electric sparks to ignite the mixture. Use with the ignition system and fuel supply system to make the engine work normally, which determines the performance of the engine to a large extent. Spark plugs are daily consumables for cars. As the core of a car engine, the performance of the spark plug can almost directly determine the performance of the car, so you should always check the car's spark plug.

Usage: test spark plug performance and ignition intensity.

 

🔥Functions:

1. The two-hole car spark plug test detector has two test holes. You can test two spark plugs during this.

2. If you suspect that a spark plug is not working properly, you can compare and test it to make an accurate assessment.

3. To test the performance of the spark plug and ignition resistance, apply them to spark plugs for 12V petrol vehicles.

4. The double hole of the diagnostic tool of the spark plug analyzer of the spark plug tester can be adjusted.

5. You can adjust the working frequency between 1000 RPM and 5000 RPM. The higher the frequency, the stronger the spark strength.

 

✨Characteristics:

1. Double hole test and save time: ANCEL car spark plug tester can perform double hole test and analog engine operation simultaneously, which is much more efficient and time-saving.

2. 0-6000rpm working frequency: ANCEL car spark plug tester is designed with adjustable working frequency, the range can reach 0-6000rpm. It can be adjusted according to your needs.

3. Wide application: 12V gasoline vehicles car spark plugs, input voltage 100V-240V.

4. Easy Plug and Play Operation: Easy operation, plug and play. Comes with indicator light, the status of the spark plug can be displayed more intuitively.
