1. General Description

A. Widely used in ship, automobile, chemical manufacture, metallurgy, machine, household appliance and many other fields. It can pick up and amplify the weak audio signals via a sensitive piezoelectric sensor, and distinguish the normal/abnormal signal and its location.

B. Designed to help locate the source of excess bearing and machine noise easily at low cost. It is an ideal easy to use listening device for mechanical generated noise in all types of applications.

C. Used to quickly locate the source of engine noise such as piston slap, worn gears and bearings, damaged valves, water pump failure, blown gaskets. Also useful tracking down dashboard rattles and squeaks.

2. Main applications

A. Rapidly detect the machine noise from a diesel engine, an air cylinder or an automobile, and exactly find out the malfunction position.

B. Used to check the piston slap, worn gears, damaged valves and bearings, water pump failure in industry.

C. Monitor the automatic assembly line to ensure proper operation.

D. Identify the abnormal noise from an engine or a motor to avoid accident.

E. Monitor the working of all kinds of axletrees.

F. Monitor the working of a ship or vessel.
