This Electrical Stethoscope is a high performance maintenance tool which is particularly suiable for use in machine noise detection. 

By using this detector, you can easily detect and find the early hidden trouble of a machine so that you can service the machine in an early time to ensure the machine' proper operation and avoid any damage or economic loss.

This detector consists of IC circuit and transistor.

It features a small size and a light weight. It is very useful and easy to operate, a powerful tool for a maintenance man.

The detector's probe has a high-sensitivity so that you can use the unit to detect and locate the position where the machine's certain noise come from.

All kinds of noise can be detected, such as valve's quiver sound, tappet's tremolo, a loose piston's sound, tremolo of gear or pump and sound of relay solenoid.

In addition, it can also be used to judge the working conditions of various motors, internal-combustion engines, diesel engines, engines, household appliances, the automatic assembly line, and so on.

In general, this unit can be widely used in ship, automobile, chemical manufacture, metallurgy, machine, household appliance and many fields.

Main Application

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