Spark plug tester with adjustable ignition simulation

This spark plug tester with adjustable ignition simulation offers a reliable solution for testing spark plug performance under simulated engine conditions. By rotating the control dial, the device can simulate ignition frequencies from 0 to 6000 RPM. A higher setting increases spark intensity, making it easy to assess plug performance under load.

Key features

• Dual spark plug socket – enables simultaneous testing and comparison of two spark plugs
• Voltage indicator – shows real-time testing voltage
• Power indicator – signals when the device is active
• Rotary switch – sets simulation frequency from 0 to 6000RPM
• Power port – for connecting external power supply
• Protective cover – shields the user from accidental electric contact

This tool is ideal for workshops and technicians needing to quickly diagnose weak or failing spark plugs before installation. The device ensures both safety and precision, helping reduce misfires caused by undetected plug issues.
