주요 특징
Three Spark Plug Positions with Digital Speed Control
1 Reference + 2 Test Plugs
Test one standard or new spark plug together with two test spark plugs for a more straightforward visual comparison of spark strength and performance.
200-9000 RPM Simulation
Adjust the bench firing-rate setting from 200 to 9000 rpm and compare the reference and test plugs at the same displayed setting. Treat the result as a relative in-air observation, not proof of spark performance under cylinder pressure or load.
Three-Hole Design
The three-hole layout supports simultaneous comparison of three spark plug positions, making it suitable for efficient 12V automotive spark plug checks.
Adjustable Test Hole Height
The adjustable test hole height helps support longer spark plug ends and improves compatibility for models that use longer plug structures.
Digital RPM Display
The LCD digital backlit display clearly shows the simulated RPM, helping users control test conditions with better visibility.
투명 안전 커버
The protective cover lets users observe spark behavior while reducing direct spark exposure during operation.
Accessible Test Controls
The test holes, transparent cover, digital display and buttons are grouped together for spark plug comparison.
External Adapter Power
SPT301 uses AC 110V / 220V input power and DC12V output. Confirm local power compatibility before use.

서비스 워크플로
Install a Reference and Compare Under Cover
Place The Spark Plugs
Insert the standard spark plug into the standard test hole, then insert the spark plugs to be tested into the test holes.
보호 덮개를 닫으세요
Cover the protective cover before testing to reduce direct spark exposure and improve safety during observation.
전원을 연결하고 시작하세요
Plug the power adapter into the side power interface, connect the power supply, and turn on the power switch.
RPM을 조절하고 관찰하세요
Use the “+” and “-” buttons to adjust the working frequency, then observe the spark plug test status through the protective cover.
안전한 사용
Treat the Bench Spark as a Relative Check
Power Off Before Installing Plugs
Do not insert or remove spark plugs while the power supply is connected. Turn off the tester before installing, removing, or repositioning spark plugs.
Close The Safety Cover
Close the transparent protective cover before testing. It helps reduce direct exposure to sparks during visual observation.
Do Not Touch During Operation
When the spark plug is running, the voltage can reach tens of thousands of volts. Do not touch the spark plug directly with bare hands.
Use Correct Input Power
Use AC 110V / 220V ±10% input power as specified for the SPT301 spark plug tester.
Use For Suitable Spark Plugs
SPT301 is suitable for common 12V automotive spark plug testing and motorcycle spark plug checks. Confirm size and fitment before testing unusual plug types.
Store In A Dry Place
When not in use, store the tester in a dry, ventilated place. Avoid hot, humid, non-ventilated areas and contact with corrosive liquids.
Compare Bench Results
Compare spark behavior across plugs, then confirm suspected ignition faults on the vehicle.
Inspect Before Operation
Tighten loose parts before operation and avoid rubbing the housing against rough surfaces. Do not overload the equipment; keep the safety guard complete and reliable. Stop use if wiring is aging or damaged.

구매자 질문
점화 플러그 장착 및 비교 관련 질문
What Spark Plugs Can SPT301 Test?
SPT301 is designed for common 12V automotive spark plug testing and motorcycle spark plug checks. It supports long spark plug testing and adjustable test hole height, but users should confirm fitment before testing unusual plug sizes or special structures.
How Many Spark Plugs Can It Test At The Same Time?
SPT301 has three test positions. It can compare one standard or new spark plug with two spark plugs to be tested, helping users observe spark strength and performance differences more directly.
Can The Simulated RPM Be Adjusted?
Yes. Use the “+” and “-” buttons to adjust the working frequency. SPT301 supports 200-9000 RPM simulation, and the digital display shows the simulated RPM during testing.
What Power Supply Does SPT301 Use?
SPT301 uses AC 110 V / 220 V ±10% input power and DC 12 V output. Use the supplied power adapter and confirm local power compatibility before use.
Do I Need To Close The Protective Cover Before Testing?
Yes. Close the protective cover before testing. The tester generates high-voltage sparks during operation, so do not touch the spark plug directly and do not insert or remove spark plugs while the power supply is connected.
What Is The Difference Between SPT301 And SPT360?
SPT301 has three test hole positions and supports 200-9000 RPM, LCD digital backlit display, adjustable hole position height, and long spark plug testing. SPT360 has five test hole positions for users who need more comparison capacity.
패키지 구성품은 무엇인가요?
