Review: good quality and affordable - i love it
Review: Didn't work for me :( - Ultrasonic leak detector didn't work for me. I first tried it on a known leak on my air compressor line. Then I tried it on a small known leak on a refrigerant system receiver nothing. Tried it on a coil, nothing. I boxed it back up and sent it back.

## Features

- 【Professional-Grade Ultrasonic Detection】This leak detector is engineered for automotive and industrial applications. It accurately pinpoints leaks by sensing the high-frequency sound (36-44KHz) produced by escaping air, gas, or vacuum leaks, helping you diagnose issues in engines, compressors, and pressurized systems with precision.
- 【Versatile & Multi-Purpose Use】Suitable for a wide range of professional uses, including detecting leaks in car air conditioning systems, industrial gas lines, vacuum systems, and air brakes. The included contact probe also allows you to listen to internal mechanical sounds from bearings, valves, and pumps for diagnostic purposes.
- 【High Sensitivity & Adjustable Volume】Features a sensitive ultrasonic microphone and a rotary volume control knob to amplify faint sounds, allowing you to filter out background noise and focus on the leak. The LED indicator lights provide a visual signal of the leak's intensity for clear confirmation.
- 【Durable Design & Complete Kit】Built for the workshop environment, this tool comes with a sturdy build and a full set of accessories, including a focusing cone for long-range detection, a contact probe for mechanical diagnosis, and a comfortable headset for audible feedback in noisy settings.
- 【Important Usage Guidance】PLEASE NOTE: This tool is designed for finding air, gas, and vacuum leaks in automotive and industrial contexts. It is not designed for detecting leaks in water pipes, plumbing, swimming pools, or tires. For best results, please use the included test leak to verify functionality before use.

## Questions & Answers

**Q: Can underground water pipe leaks/water pipes in underground passages be detected?**
A: No. If the pipe is buried under soil or concrete, the ultrasound cannot escape to the surface, so the device will not pick it up. Our detector only senses ultrasound traveling through open air.

**Q: It can power on normally, but after startup, there is no signal at all. Is it a device issue? What can the customer do?**
A: Try using the matching ultrasonic transmitter to see if there is a signal. Perform initial tests in a quiet, indoor environment away from background noise.

**Q: Is it possible to deteck leaking from heating floor or heating pipe embedded in concrete?**
A: Sorry, EM2268 is unable to detect,It's a low pressure system.
