It accepts 100–240V input and provides an adjustable frequency to mimic real crankshaft RPMs, making bench diagnosis and roadside troubleshooting faster and safer. Rugged ABS construction and a user-friendly protective cap reduce electric shock risk while you inspect ignition intensity.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tester reveal a weak or faulty spark plug?\u003c\/h3\u003e\n\u003cp\u003eThe tester powers two spark plugs simultaneously so you can compare the visible spark intensity and consistency between a known-good plug and the suspect plug. By adjusting the simulated rpm, you can observe how the spark behaves across different engine speeds and spot intermittent or weak ignition.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual 12 mm sockets let you test two plugs side-by-side for direct comparison.\u003c\/li\u003e\n\u003cli\u003eAdjustable 0–6000 rpm simulation to reproduce low and high engine conditions.\u003c\/li\u003e\n\u003cli\u003eVisual spark observation through the protective cover to spot weak or inconsistent arcs.\u003c\/li\u003e\n\u003cli\u003eWorks with most 12V gasoline vehicle spark plugs and motorcycle plugs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the AUTOOL tester safe and easy to use at the roadside or in the shop?\u003c\/h3\u003e\n\u003cp\u003eYes—its plug-and-play design means you connect the adapter, fit the plugs, close the protective cover, and start the test.
