UNI-T UT662B High Precision Ultrasonic Water Leakage Detector
The UNI-T UT662B Multifunctional Intelligent Water Leakage Detector collects pipe leak noise signals via its sensor. After processing by the host unit, the visualized spectrum, signal strength and AI-assisted locating prompts are displayed on the built-in 5″ LCD screen and output simultaneously to the headphones.
With a 1 Hz – 8000 Hz frequency bandwidth, adjustable frequency filters and 80 dB (10-level) signal gain, the UT662B allows users to combine AI recognition results with a comparison of the spectrum and audio signals to quickly pinpoint the leak and efficiently complete household pipe leak detection, with a measuring depth of about 100 cm using the included vertical sensor.
