Metal Detector Visit the Store Metal Detector Review: Good for refrigerant leaks. - This is very good for finding medium to large leaks on condenser coils. Review: Doesn’t work cheap material - Didn’t work held it up to many electric devices and speakers got nothing to show up and I can hear the sound. Also was beyond cheap feeling. Not sure why this gets even decent reviews ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B8GFCDL | | Batteries | 2 9V batteries required. | | Batteries Included? | No | | Batteries Required? | Yes | | Battery Cell Type | Zinc Carbon | | Best Sellers Rank | #70,649 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #63 in Leak Detection Tools | | Color | Black | | Customer Reviews | 3.6 3.6 out of 5 stars (144) | | Date First Available | March 6, 2018 | | Description Pile | 9V battery | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 3.03 pounds | | Manufacturer | Zhangzhou Haimao Dianzi Keji Co., LTD | | Material | ABS | | Package Dimensions | 10.51 x 10.35 x 4.49 inches | | Power Source | Battery | | Warranty Description | 1 Year | ## Images ![allsun Pro Ultrasonic Leaking Detector Transmitter Auto Noise Finder, Electronic Stethoscope HVAC Machine Noise Monitor 36-44KHz, Air Gas Water Leak Diagnosis Tool - Image 1](https://m.media-amazon.com/images/I/51Rwzw4sJ1L.jpg) ![allsun Pro Ultrasonic Leaking Detector Transmitter Auto Noise Finder, Electronic Stethoscope HVAC Machine Noise Monitor 36-44KHz, Air Gas Water Leak Diagnosis Tool - Image 2](https://m.media-amazon.com/images/I/61AStL-or3L.jpg) ![allsun Pro Ultrasonic Leaking Detector Transmitter Auto Noise Finder, Electronic Stethoscope HVAC Machine Noise Monitor 36-44KHz, Air Gas Water Leak Diagnosis Tool - Image 3](https://m.media-amazon.com/images/I/612uFkxUXdL.jpg) ![allsun Pro Ultrasonic Leaking Detector Transmitter Auto Noise Finder, Electronic Stethoscope HVAC Machine Noise Monitor 36-44KHz, Air Gas Water Leak Diagnosis Tool - Image 4](https://m.media-amazon.com/images/I/71kByA6iAVL.jpg) ![allsun Pro Ultrasonic Leaking Detector Transmitter Auto Noise Finder, Electronic Stethoscope HVAC Machine Noise Monitor 36-44KHz, Air Gas Water Leak Diagnosis Tool - Image 5](https://m.media-amazon.com/images/I/51A816X9TpL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good for refrigerant leaks. *by E***M on August 9, 2025* This is very good for finding medium to large leaks on condenser coils. ### ⭐ Doesn’t work cheap material *by M***I on April 30, 2026* Didn’t work held it up to many electric devices and speakers got nothing to show up and I can hear the sound.
