## Features

- Precise Localization.L series 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 L series underground water leak detector 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.
