Click to enlargeBefore You Order And Use
SPT360 is a high-frequency ignition tester. Review the protective cover, power-off handling, high-voltage warning, storage, and inspection notes before testing spark plugs.
Close The Protective Cover
Close the transparent protective cover before testing. Do not run the spark plug tester with the cover open.
Power Off Before Handling
Do not insert or remove spark plugs while the power supply is connected. Turn off the power first.
High Voltage Warning
During operation, spark plug voltage can reach tens of thousands of volts. Do not touch the spark plugs directly with bare hands.
Use A Safe Environment
Use the tester in a suitable dry environment. Avoid hot, humid, or non-ventilated storage conditions.
Inspect Connections
Regularly check parts that need tightening or connection. Tighten loose parts in time to keep the equipment safe.
Maintain The Circuit
Check the circuit section thoroughly during maintenance and replace aging wires or worn parts when needed.
Care Reminders
- Do not overload the equipment during testing.
- Keep safety guards complete and reliable.
- Avoid rubbing the housing against rough surfaces.
- Avoid contact with corrosive liquids.
- Store the product in a dry place when not in use.
Key Features
SPT360 is built for fast comparative spark plug checks with five test holes, digital sensing, LCD RPM control, long spark plug support, working condition simulation, and simple plug-and-play operation.
Five-Hole Comparative Testing
Test up to five spark plugs at the same time. Use one standard spark plug and compare the remaining test plugs for clearer performance judgment.
Digital RPM Display
The LCD digital backlit screen displays the simulated speed setting, helping users adjust and observe test conditions more precisely.
200-9000 RPM Simulation
The tester simulates engine speed from 200 to 9000 rpm. Higher frequency produces stronger spark plug intensity for comparison.
Adjustable Test Hole Height
The adjustable hole position height helps the SPT360 support testing of long spark plugs.
Safety Protection Cover
The transparent protective cover helps improve safety and allows users to observe spark behavior during testing.
Simple Operation
Insert the spark plugs, connect power, close the cover, turn on the switch, and adjust the working frequency with the RPM buttons.
SPT360 Product Specifications
SPT360 uses digital sensing, AC 110V/220V input power, DC 12V output power, 200-9000 rpm analog speed, and five test hole positions for high-frequency spark plug comparison.

How To Use
Use the SPT360 by inserting the standard spark plug and test plugs, connecting the power adapter, closing the protective cover, and adjusting the RPM frequency with the control buttons.
Insert Spark Plugs
Insert the standard spark plug into the standard test hole, then insert the spark plugs to be tested into the remaining test holes.
Connect Power
Plug the power adapter into the side power port on the tester. Confirm that the indicator light turns on.
Close The Cover
Close the transparent protective cover before testing to reduce exposure to high-voltage spark activity.
Start And Adjust RPM
Turn on the power switch and press the RPM “+” or “-” buttons to adjust the working frequency.
Compare Spark Performance
Observe the spark intensity of each plug. The higher the frequency, the stronger the spark plug intensity during the simulated test.
Use Notes
- Turn off the power before inserting or removing any spark plug.
- Do not touch spark plugs directly during operation.
- Keep the protective cover closed while testing.
- Use the standard test hole for the reference spark plug and compare test plugs against it.
- Use the digital RPM controls to adjust frequency gradually.
