A compact, professional underground water leak detector designed to locate pipeline leaks by detecting leak noise and guiding the operator to the source. Key benefits Pinpoint leak location quickly by listening to the noise produced at the leak source, reducing time spent searching. Improved detection accuracy through an external headphone sensor that provides clear audio and supports confident judgment. Flexible frequency control lets you adapt to different environments and pipe conditions for more reliable results. Lightweight and portable design simplifies transport and deployment to field sites. Main features Leak detection method: detects acoustic noise from underground pipelines to determine leak position. Audio monitoring: external headphone sensor for direct listening; wear headphones to evaluate sound and confirm leak location. Frequency control: four adjustable gears and continuous tuning across 200 Hz to 3000 Hz, allowing selection of the most appropriate frequency for the specific environment. Size and weight: main unit weighs approximately 900 g, making it easy to handle during field inspections. Carrying and protection: supplied with a protective suitcase and a main unit backpack for secure transport and storage. Performance and usability Designed for straightforward operation in the field. The frequency range and multiple gear settings enable operators to adapt to pipe material, depth, and background noise. External headphone sensor improves signal clarity for accurate auditory diagnosis. Compact main unit and included carrying options support daily use at multiple sites. Typical applications Locating leaks on residential and commercial water service lines buried under sidewalks, yards, or pavements. Tracing leaks on municipal water mains and distribution networks where pinpointing the source reduces excavation. Inspecting irrigation systems and industrial pipelines for audible signs of leakage in noisy or complex environments. What to expect during use Connect and wear headphones, adjust frequency and gear settings based on site conditions, then scan along the pipeline route to identify the strongest leak noise and mark the location for . This detector provides practical acoustic leak locating capabilities with adjustable frequency control, clear audio monitoring, and portable protection for field use.
