【Product Applications】 Mainly used in engines and other mechanical devices, it can quickly measure the mechanical noise emitted by diesel engines, cylinders and automobiles, and accurately locate the position of mechanical failures. 【Product Features】 * Equipped with a sensitive piezoelectric vibration sensor, it can receive audio signals and amplify them as needed. It can also determine if the signal is within the normal audio range and its direction. * The design aims to quickly measure and noise sources that exceed the tolerance range at a low cost. * It can quickly measure the following mechanical noises, such as: pistons, worn gears and, broken valves, faulty water pumps, gaskets, etc., and can also track and locate noise on the car dashboard.
