【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.
【DETECT HIDDEN MACHINE FAULTS EARLY & SAVE COSTS】Pinpoint the exact source of abnormal noises (valve quiver, tappet tremolo, loose piston, gear/pump tremolo, relay solenoid) in engines, motors, bearings, and machinery before they cause expensive breakdowns. Essential predictive maintenance tool for mechanics and engineers.
【HIGH-SENSITIVITY DIAGNOSIS IN NOISY ENVIRONMENTS】Features a powerful probe and amplifier detecting subtle vibrations (100Hz-10kHz) even amidst loud ambient noise (up to 100dB). Clearly hear issues others miss through the included comfortable earphones.
【TOOL FOR MULTIPLE APPLICATIONS】 Go beyond noise detection! Verify liquid flow/blockages in pipes, monitor bearings, check engine/motor health, inspect boilers/reaction vessels, and maintain assembly lines, vehicles (cars, ships), and household appliances reliably.
【DURABLE & READY-TO-USE INDUSTRIAL DESIGN】Powered by a single 9V battery (included), this lightweight (240g) yet robust tool operates reliably from -10°C to 55°C. Kit includes versatile LONG and SHORT probes, earphones, carry bag, and clear instructions for immediate use.
【Prevent Accidents & Ensure Optimal Operation】Quickly identify malfunction positions in diesel engines, cylinders, or automobiles. Detect abnormal sounds in critical equipment to prevent accidents and ensure machines, motors, and production lines operate smoothly and safely.
【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.
The ultrasonic leak detector is designed to locate leaks in pressure and vacuum systems.It can be used to detect and locate the source of the ultrasonic emissiongenerated by gas or liquid flowing through a small restrictive opening. ltuses the advanced ultrasonic sensing technique and features small sizelight weight, reliable detection, easy use and utility.
Power supplied by 2 pieces 9V, 6F22 battery (Battery Provided). Both the transmitter and detector require separate installation of batteries, and the positive and negative terminals of the batteries should be correctly installed. Frequency Response: 40kHz ±2kHz. Measure distance: Min.about 5cm, max.about 2-3 meters. Operating Condition: temperature: 0°C~40°C, relative humidity:<80%.
When using, the transmitter must be placed inside the object being tested. For example, when measuring the airtightness of a car, it is necessary to place the transmitter inside the car and close the doors and windows. Then use the detector to track the exterior of the windows and door seals to locate the leak.
This ultrasonic leak detector is not suitable for testing pipeline leaks, air conditioning leaks, or pool leaks, cabin leaks, etc. It can only be used for ultrasonic gas leaks; At the same time, this product is not suitable for low-pressure environments, such as not being able to detect air leaks in inflatable mattresses or hot tubs. If the air pressure is too low, the product may not function properly.
This product includes adjustable headphone for detector, allowing you to work even in noisy environments. Includes a customized storage bag to protect the product from external damage and make it easy to carry when used outside.
【Quick Leak Location】Ultrasonic leak detector adopts advanced ultrasonic sensing technology, which is specially used to detect the leakage of gas, liquid, etc. Air leak detector can quickly and accurately find gas or liquid leaks in various pressure or vacuum systems. Ultrasonic leak detector can be used to detect the tightness of cabins, car cockpits, refrigerators, containers, etc., and can also be used to track and locate leaks in doors and windows, pipes, tires, and refrigeration equipment.
【High Sensitivity Sensor & Adjustable Sensitivity】Ultrasonic leak detector adopts advanced high-quality sensor with high sensitivity, which can respond quickly and detect tiny leaks, providing you with stable and high-precision detection. The sensitivity of the ultrasonic air leak detector can be manually adjusted according to the detection environment. Adjust to the required sensitivity, the measurement accuracy will be higher (Frequency Response: 40KHz ± 2KHz).
【Sound & Light Dual Alarm Prompt】When ultrasonic waves are detected, the LCD indicator of the ultrasonic leak detector will light up, and ultrasonic leak detector will issue rapid ticking sounds to remind you at the same time. Our ultrasonic leak detector comes with a headset that quickly captures the location of leaks with even the tiniest of sounds. The closer the probe is to the leak, the faster the frequency and the higher the pitch of the ticking sound in the headset.
【420MM Flexible Probe&Foldable Headset &Portable Handbag】The probe of ultrasonic leak detector is 420MM long and can be bent at will, so the position of the leak can be easily accessed and detected even in difficult and hard-to-reach areas.
