## Description

allsun Ultrasonic Leak Detector Diagnostic Stethoscope 36-44kHz Air/Contact Probe,Kit w/Rotary Volume,Tone Generator,Find Vacuum Gas Seal Faults,Auto& Industrial Leak Detection Tool

## 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.
