The LED bar graph and adjustable headphone volume provide dual confirmation for accurate leak localization. - 【DUAL PROBES FOR INSPECTIONS】Includes specialized probes: The Air Probe excels at detecting pressurized leaks & electrical discharges (test by rubbing fingers 60cm away for a "sandpaper-on-wood" response). The Contact Probe is ideal for diagnosing ultrasound within machinery casings (gears, bearings, valves, steam traps) - simply rub the probe rod tip. - 【OPTIMIZED DETECTION & OPERATOR COMFORT】Features a rotary volume knob for precise headphone adjustment. Set volume just above background hiss for maximum sensitivity without fatigue. Remember: Higher volume doesn't increase sensitivity, correct setup prevents exhaustion during long inspections. - 【TEST ENCLOSURE SEALS & LOCATE LEAKS EFFICIENTLY】Includes a Tone Generator to check seal integrity in non-pressurized spaces (e.g., car doors/windows/roofs, enclosures). Place the generator inside (or near suspect areas for large spaces), then sweep the receiver to find leaks. Suitable for automotive QA and building diagnostics. - 【INTUITIVE SCANNING TECHNIQUES】Utilize the LED graph and headphone sound together to zero in on leaks. As you approach the leak source, decrease headphone volume to refine location based on LED intensity. Effective even for slight leaks where LED movement is minimal.Power supply is 9 V alkaline battery. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | allsun | | Style | Enclosure Seal Tester | | Power Source | Battery Powered | | Color | Blue | | Item Weight | 2.16 Pounds | | Alarm | Audible, Visual | | Operating Humidity | 95 percent | | Upper Temperature Rating | 40 Degrees Celsius | | Sensor Type | Ultrasonic | | Material | ABS | | Manufacturer | Zhangzhou Haimao Dianzi Keji Co., LTD | | UPC | 788537552277 | | Item Weight | 2.16 pounds | | Product Dimensions | 11.1 x 5.16 x 9.5 inches | | Batteries | 2 9V batteries required. | | Is Discontinued By Manufacturer | No | | Batteries Included? | No | | Batteries Required? | Yes | | Battery Cell Type | Zinc Carbon | ## Product Details - **Brand:** allsun - **Style:** Enclosure Seal Tester - **Power Source:** Battery Powered - **Color:** Blue - **Item Weight:** 2.16 Pounds - **Alarm:** Audible, Visual - **Operating Humidity:** 95 percent - **Upper Temperature Rating:** 40 Degrees Celsius - **Sensor Type:** Ultrasonic - **Material:** ABS ## Images ![Ultrasonic Detect Tool Stethoscope - Image 1](https://m.media-amazon.com/images/I/61oeBDMG-1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great in auto repair shop, much better than the bluepoint mic. *by W***X on April 11, 2025* Pinpointed an axle bearing growl with shop radio right next to you. The bearing was barely bad and thought it could be the carrier (in diff) bearing but was axle bearing. This tool nailed it. Been using the Bluepoint microphone for over a decade or more, that thing going in garbage, had better luck with using a hose or screw-driver to pick up noise. Tried to use on injectors but secondary voltage too noisy when that close. But it's awesome away from secondary noise. ### ⭐⭐⭐⭐ Works well, but the tube can pick up interference. *by A***M on April 2, 2025* Extremely accurate, but can be tricked by the tubes in tight spaces. Try using it without the tubes if there is too much background noise. ### ⭐⭐⭐⭐⭐ Works for hvac *by R***N on October 4, 2024* I do transport refrigeration and had a hard time finding leaks I’ve used sniffers and bubbles this thing you can hear small leaks undetectable by a sniffer even boost leaks air brake leaks also has frequency transmitter you can check seals with like freezers or back of a refrigerator truck or fridge well worth the money although the light gage is not that sensitive but you’ll definitely hear leaks also has a stethoscope great value most useful tool I’ve bought for my trade ## Frequently Bought Together - allsun Ultrasonic Sound Leakage Detector Kit for Detecting Refrigerant Air Gas Liquid leaks Diagnosis Tool - Appion MGAVCT 1/4" MegaFlow Vacuum-Rated Valve Core Removal Tool - Elitech LMC-100A+ 220Lbs Refrigerant Scale Electronic Freon Charging Recovery Weight Scale for HVAC with Case --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/71114185-ultrasonic-detect-tool-stethoscope](https://www.desertcart.be/products/71114185-ultrasonic-detect-tool-stethoscope) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-20*
