SPT301 Spark Plug Tester

The AUTOOL SPT301 Spark Plug Spark Tester simulates the high-voltage ignition environment of an engine to test the ignition performance of spark plugs. The principle is to ignite the spark plug with high-voltage current, observing the strength, stability, and color of the spark to determine if the spark plug is functioning properly. The tester can simulate different working conditions (such as varying engine speeds) and detect common issues such as weak sparks, intermittent sparks, or abnormal colors, helping to quickly diagnose whether the spark plug needs to be replaced or adjusted.

AUTOOL SPT301 Spark Plug Spark Tester Features

Three-Socket Testing with Real Simulation: The Spark Plug Spark Tester features a three-socket testing function, allowing you to compare three spark plugs simultaneously, improving efficiency. It accurately simulates real engine working conditions, making the testing process more efficient and delivering more precise results.

Adjustable Testing Socket Height: The SPT301 Adjustable Spark Tester is compatible with vehicles such as BMW, Volkswagen, Audi, and other models with longer spark plug ends, offering a wider range of applications.

Comparison Testing: The SPT301 Spark Plug Tester allows simultaneous testing of two spark plugs along with a new one, providing more intuitive and clearer results.

Digital Screen Display: The SPT301 Adjustable Spark Tester and ignition tool clearly display simulated engine RPM, enhancing control precision.

Adjustable Working Frequency and Protective Cover: The Automotive Spark Plug Spark Tester operates at a working frequency of 200-9000 RPM. The higher the frequency, the stronger the spark intensity. The working frequency can be conveniently adjusted using the control buttons to suit your specific needs. With excellent testing and ignition performance, the tester is also equipped with a protective cover to safeguard against the risk of electric shock.

Three-year Warranty: For damages caused by non-human factors, AUTOOL promises to provide free replacement parts within three years. If you have any requests, please feel free to contact us, and we will respond promptly within 24 hours.
