Locating leaks in indoor plumbing systems or buried outdoor pipelines can be a time-consuming task for maintenance professionals. The PQ125 Series Portable Leak Detector, developed by Hunan Puqi Geologic Exploration Equipment Institute, provides a versatile solution for both indoor and outdoor water pipe leak identification.

   The system supports multiple inspection modes, including survey mode and positioning mode, allowing operators to quickly scan large areas before pinpointing the exact leak location. By using high-sensitivity acoustic sensors, the device detects leak sounds transmitted through pipes, walls, and surrounding materials.

   The detector offers a wide frequency acquisition range of 1 Hz–10 kHz, ensuring reliable performance in various inspection scenarios. The built-in 24-bit ADC and 48 kHz sampling technology capture detailed acoustic signals, which are then analyzed through intelligent algorithms.

   With centimeter-level positioning accuracy, the system helps technicians determine leak locations efficiently. Its 7-inch LCD display, adjustable signal gain, and Micro SD storage for recording inspection data further enhance usability.

   Combined with its lightweight 0.6 kg design and rechargeable 7.4V 6600mAh battery, the PQ125 detector provides a practical solution for modern pipeline maintenance operations.
