## Description

desertcart.com: 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) : Industrial & Scientific

Review: Inexpensive tool but worked OK. - For an inexpensive toll it worked just fine. Not terribly sensitive and as others have commented, it has to be touching a surface to work. You can’t wave it in the air and expected to pick up any sound whatsoever.
Review: Nice product, poor description - This is a decent-quality *contact microphone*, and quite sensitive for detecting vibrations and internal machinery noise. However, it barely picks up ambient sounds, so I was unable to use it to localize the hissing air leak in a pneumatic system. The description says "Air Leak Detector", but I found it unsuitable for that purpose and returned it.

## Features

- 【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.

### ⭐⭐⭐⭐⭐ Inexpensive tool but worked OK.

### ⭐⭐⭐⭐⭐ Nice product, poor description
*by L***R on February 16, 2023*

This is a decent-quality *contact microphone*, and quite sensitive for detecting vibrations and internal machinery noise.

### ⭐⭐⭐⭐ Very Useful.
*by A***R on September 12, 2025*

Works great. It's very interesting to listen to the valve train and fuel pulses on my car's engine. With this device, I believe I know the source of this noise is just an artifact of the engine's design, and nothing to be concerned with.
