PQWT L4000 Indoor/Outdoor Leak Detector
Floor-Optimized
5m Depth
Engineered as the definitive solution for sub-floor leak detection, this professional tool offers powerful 5m outdoor reach and precise 0.5m indoor sensitivity. Move seamlessly from scanning your yard to pinpointing the exact source beneath tiles, concrete, or hardwood—all with one reliable device.
Floor-Focused Dual-Sensor System
The L4000 is optimized for accuracy where it matters most: at ground level. Its specialized two-sensor kit targets different surfaces with precision. Outdoor Medium Sensor: Efficiently scans large areas of hardened ground or soft soil (grass, mud) to narrow down the leak zone. Indoor Triangular Ground Sensor: This is the core of floor detection. Its stable, ground-hugging design ensures maximum contact and signal clarity. It captures clean acoustic vibrations from pipes below, delivering adjustable audio feedback that leads you directly to the leak's source with minimal guesswork.
See It, Hear It, Find It Fast
Experience intuitive leak location through multi-sensory guidance. High-Definition Visual Guidance: The clear display shows real-time signal strength bars and spectral waveforms. Watch as the visual peak intensifies directly over the leak. Professional Audio Confirmation: Connect the included headphones. The triangular sensor transmits distinct, amplified leak sounds—hisses, drips, or flows—allowing for decisive audio verification to complement the on-screen data.
Built for Reliability Across Environments
A tool as dependable as your work demands.
Rugged & Ready: Performs in temperatures from -20°C to +50°C. The main unit is lightweight (0.75kg) for all-day use.
Extended Operation: Features a long-life battery with 15-hour standby and convenient 5V USB charging.
Global Professional Support: Includes an 11-language interface and is backed by a 2-year warranty for confident, worldwide use.
Stop the damage at its source. Choose the L4000—the floor leak specialist for professionals who value precision.
