allsun Pro Ultrasonic Leak Detector & Industrial Stethoscope,High Sensitivity Machine Diagnostic Tool for Engine Noise, Bearing, Valve, Pump, Pipe Flow,Mechanic Tool Kit(Includes Long/Short Probe & Carry Bag)

【DETECT HIDDEN MACHINE FAULTS EARLY & SAVE COSTS】Pinpoint the exact source of abnormal noises (valve quiver, tappet tremolo, loose piston, gear/pump tremolo, relay solenoid) in engines, motors, bearings, and machinery before they cause expensive breakdowns. Essential predictive maintenance tool for mechanics and engineers. 【HIGH-SENSITIVITY DIAGNOSIS IN NOISY ENVIRONMENTS】Features a powerful probe and amplifier detecting subtle vibrations (100Hz-10kHz) even amidst loud ambient noise (up to 100dB). Clearly hear issues others miss through the included comfortable earphones. 【TOOL FOR MULTIPLE APPLICATIONS】 Go beyond noise detection! Verify liquid flow/blockages in pipes, monitor bearings, check engine/motor health, inspect boilers/reaction vessels, and maintain assembly lines, vehicles (cars, ships), and household appliances reliably. 【DURABLE & READY-TO-USE INDUSTRIAL DESIGN】Powered by a single 9V battery (included), this lightweight (240g) yet robust tool operates reliably from -10°C to 55°C. Kit includes versatile LONG and SHORT probes, earphones, carry bag, and clear instructions for immediate use. 【Prevent Accidents & Ensure Optimal Operation】Quickly identify malfunction positions in diesel engines, cylinders, or automobiles. Detect abnormal sounds in critical equipment to prevent accidents and ensure machines, motors, and production lines operate smoothly and safely. This Electrical Stethoscope is a high performance maintenance tool which is particularly suiable for use in machine noise detection.
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.
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.
