Review: Tech 50 years. - Works very well,I am in the a/c and refrigeration business. And it works very well. You just haft to learn the sound, and understand it works of of sound waves. Would highly recommend it.
Review: Ultrasonic - Had the opportunity to test this Ultrasonic Leak detector, Today I ran over a 1/4” chisel and it imbedded in my Tire. I filled the tire back up with Air and drove to the nearest Autoparts store. Using pliers I pulled the chisel out of the tire and plugged the hole with a repair kit. Would you know I couldn’t hear the leak with my ears but using this ultrasonic I was picking up the leak 4 feet away. I plugged the hole again and the second time was the charm. It didn’t pick up the leak this time. Saved my butt. I have a Amprobe Ultrasonic but it was getting old (Since 1995) time to retire it. This one has checked out so far, Let’s see how it does on Refrigerant leaks. Longevity remains to be seen. Solid 4.5 stars.

## Features

- 【DETECT LEAKS IN SECONDS】Locate even faint air leaks, electrical coronas, and internal mechanical issues (like failing bearings, valve leaks, or steam trap faults) using directional air and contact probes. 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.

### ⭐⭐⭐⭐⭐ 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.
