Autool SPT301 | Spark Plug Tester
The Autool SPT301 is a digital spark plug tester designed to check the performance of 12V spark plugs. This device operates on a mains voltage of AC 110V / 220V and features three test holders, allowing simultaneous testing of multiple spark plugs. The operating frequency can be set via the control buttons, enabling simulation of different engine conditions.
The tester simulates engine speed in an adjustable range of 200 to 9000 RPM, displayed on a digital display. The function for comparative tests allows comparing the performance of two spark plugs with a reference spark plug. The height of the test holders is adjustable by 8 mm, making the tester suitable for spark plugs with a long shaft, such as those used in Audi, BMW, and Volkswagen engines. A transparent protective cover covers the spark plugs during testing.
Application and functionality:
The Autool SPT301 is used for diagnosing spark strength, ignition condition, and overall operation of spark plugs under simulated engine load.
- Engine speed simulation: The device can simulate the operating frequency of spark plugs at speeds from 200 to 9000 RPM to assess performance under different conditions.
- Comparative analysis: The design with three holders allows two spark plugs to be tested simultaneously and compared with a new or well-functioning spark plug.
- Digital display: The digital screen shows the set speed, allowing precise control of the test parameters.
- Adjustable test holders: The height of the test holders can be adjusted for compatibility with spark plugs with a longer shaft.
- Protective cover: A physical cover protects the user from contact with high voltage during the testing procedure.
