The Ultrasonic Leak Detector is a compact, easy-to-use tool designed for quickly locating ultrasonic leaks caused by air, liquid, or dust. Its ergonomic design ensures a comfortable user experience with a simple key operation mode for fast detection. This device is effective in identifying leaks in tires, windows, doors, and seals by detecting ultrasonic sounds caused by high-pressure leaks. The Air Leak Detector is efficient in locating leaks in both pressurized and vacuumed areas. Using headphones, it produces distinct sounds to help pinpoint the source of the leak, while the transmitter transmits sound through enclosed spaces to identify gaps or openings, such as those in roofs. Equipped with advanced ultrasonic sensing technology, this leak finder is lightweight, reliable, and easy to use for detecting air or liquid leaks. It is ideal for finding leaks in tires, window seals, doors, and other areas of vehicles and buildings. The Gas Ultrasonic Leak Detector offers a listening device for outdoor use, further enhancing detection capabilities in hard-to-reach areas. This tool features a 40KHz frequency for precise detection of water, dust, and pressure-related leaks. It also includes an LED indicator for easy tracking and offers full utility in locating leaks, ensuring accuracy and efficiency in various leak detection applications.
