[Precise Localization] L50 water leak detector can quickly scan large areas to identify leak locations via GENERAL DETECTION MODE.In LOCATION MODE,signals from sixteen points are captured and retained in the screen's data collection box.By comparing signal strength,water leakage detector precisely locates leak point and also features a recording function. [Simple Operation] The L50 water leak detectors for home utilizes a factory-developed UI interaction system.Its touchscreen displays each functional module clearly with operational guidance,enabling even inexperienced users to easily detect leak points.For professional leak detection personnel,the water leak detection device proves an invaluable asset. [Precision Sensor] Utilizing resonance from a piezoelectric ceramic membrane at a specific frequency,sensors detect leak sounds inaudible to the human ear.Through distinct cavity structures,they filters out ambient noise from various scenarios,transmitting signals to the host device to form signal columns and frequency spectra. Professional noise-canceling headphones ensure you hear clear water flow, providing both auditory and visual assistance to pinpoint leak locations. [Original Manufacturer] The L series Multi-Sensors Water Pipeline Leak Detector is independently developed and manufactured by PQWT—Hunan Puqi Geologic Exploration Equipment Institute. As a precision instrument manufacturer collaborating with multiple universities, we have specialized in pipeline leak detection for 19 years, possessing mature production lines and a robust R&D team. [Warranty and Languages] The main unit comes with a two-year warranty and lifetime maintenance.Available in 10 languages:English, Turkish,Italian,French,Spanish,Arabic,Russian,Korean,German,Portuguese PQWT-L Multi-Sensor Water Pipeline Leak detector is the latest generation of intelligent water leak detector independently developed by Hunan Puqi Geologic Exploration Equipment Institute, This device is equipped with a triangle sensor, square sensor, medium sensor and large sensor. It is suitable for water leakage detection of outdoor water pipe, fire pipe, heating system, indoor water pipe, and underground heating floor pipe. By collecting and analyzing leakage signal,it solves the problem of pressure pipe water leak. PQWT-L Multi-Sensor Water Pipeline Leak detector collects leaking sound signal through its sensor,collected signal will be processed by host machine and displayed on the host machine screen in the form of visual spectrum and signal bars.At the same time, the sound will also be output to its earphone through the host machine.Water leakage point can be found out easily through the combination of "listening to the abnormal sound" and "observing the abnormal signal bars"
