Automobile mechanical stethoscope engine cylinder diagnostic tester detector Vibration and noise detection is one of the common methods to find faults in rotating machinery. Noise detection is widely used in engine cylinder diagnosis and other industrial fields. Intercepting the noise of the engine or other parts will help quickly and accurately find worn or damaged parts. The cylinder stethoscope is a basic portable tool for detecting vehicle failures. It will detect noise from bearings, gears, valves, crankshafts, cylinders, gearboxes...help technicians find out exactly where the problem is. Save time and increase efficiency during maintenance. Suitable for: The stethoscope can be used in all rotating and reciprocating machinery, metallurgy, petroleum, chemical, textile, electric power, mining, motors, ships, automobiles, airplanes, machine tools and various construction machinery and heavy machinery. Especially some large and complex long-term continuous operation machines.
