HY-929 Water Leak Detector with Dual Probes Acoustic Water Pipe Leak Locator Engine Noise Diagnosis, HY-929 EU Plug, HY-929 US Plug

1. Comes with two interchangeable high-sensitivity sensors: a heavy-duty zinc alloy contact probe for flat surfaces (walls, concrete floors, under tiles) and a 10cm needle pin probe designed to penetrate narrow gaps, automotive engine bays, and complex machinery.
2. Built-in micro-vibration sensor and upgraded audio signal amplification module offer -70dB ultra-high sensitivity. Easily captures micro water flow vibrations, pressure leaks, and hidden friction sounds through water pipes, cement walls, and steel pipes.
3. Integrated with active volume peak control logic that automatically suppresses sudden harsh noise bursts and sound spikes. Protects the operator's hearing health during continuous professional inspection while delivering clear, stable audio.
4. Powered by a built-in 3.7V 200mAh rechargeable lithium battery with a Type-C charging port. Low power consumption (15mA) allows up to 8–10 hours of continuous leak detection on a 3-hour full charge, perfect for full-day field inspections.
5. Lightweight host (64g) with compact dimensions (6 x 2.1 cm). Features an intuitive top power/volume knob and mode toggle switch for high/normal sensitivity adjustment. Includes 32-ohm audio output headphones for instant plug-and-play setup.
