More Details
Main highlights
- [Warranty and Languages] The main unit comes with a two-year warranty and lifetime maintenance. Available in 12 languages: English, Turkish, Italian, French, Spanish, Arabic, Russian, Korean, German, Portuguese, Polish, Vietnamese.
- [Simple Operation] The PQ125A water leak detectors for home utilizes a factory-developed UI interaction system. Its touchscreen displays each functional module clearly with operational guidance and error pop-ups, enabling even inexperienced users to easily detect leak points. For professional leak detection personnel, it proves an invaluable asset.
- [Precise Localization] The water leak detector has two leak detection modes.Users 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 strengths, the exact leak point is pinpointed.
- [Original Manufacturer] The PQ125A water leaks 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.
- [High-Precision Sensors] The PQ125A water leaks detector features two DUAL MEMBRANE RESONANCE SENSORS DMR-H40&DMR-V59 for diverse indoor environments and operational needs. Sensors utilize a double-layer piezoelectric ceramic membrane with a unique frequency to receive acoustic waves. By detecting resonance amplitude changes between leak sounds and this specific frequency, it effectively captures leak noises inaudible to the human ear.
