The AUTOOL SPT101 spark plug tester is designed to check spark plug performance and spark strength by simulating engine operating conditions. It supports dual-hole simultaneous testing, adjustable simulated speed up to 6000 RPM, and a transparent protective cover for safer observation during testing. SPT101 is a high-voltage spark plug testing device. Read the protective cover, power, and plug handling rules before connecting the tester. SPT101 focuses on simple spark plug comparison, adjustable simulated engine speed, visual test status, and safer testing with a protective cover. The SPT101 uses a compact dual-socket layout, rotary frequency control, power and working indicators, protective cover, and side power interface. SPT101 is designed for simple visual spark comparison. Always close the protective cover before testing and turn off power before inserting or removing spark plugs.
