Ultra-Sensitive Detection: Equipped with two sensor probes to ensure timely detection of leaks in basements, kitchens, bathrooms, and near appliances such as dishwashers, water heaters, or washing machines. Leak Detector Alarm Operation Logic: The leak alarm uses a cyclical mode: it first alarms for 10 seconds, then cycles through “5 seconds alarm, 3 seconds interval”. Pressing the button temporarily silences the buzzer; after 5 seconds of silence, the device will re-detect, and if the leak continues, the alarm cycle will repeat. Adjustable Loud Alarm: A 100dB loud alarm immediately alerts you to potential leaks, maximizing your safety. The alarm volume can be customized with 4 levels, cycling through high-medium-low-mute. The default volume is high. Pressing the button twice consecutively enters the volume adjustment setting. Each time a setting is completed, a yellow light flashes twice along with the volume to indicate successful setting. Suitable for quiet home environments or noisy environments. 5-Year Worry-Free Use: The built-in battery provides up to 5 years of continuous use, eliminating the need for frequent replacements and offering long-term protection. There is no time limit for the product’s lifespan. When the 5-year battery life is exhausted, the product can continue to be used after battery replacement. Water Leak Detector for RV/Car: Suitable not only for home use—such as in bathrooms, sinks, or basements- but also for monitoring potential leaks in RVs, cars, small yachts, and boats by utilizing the included accessories. Effectively prevents losses caused by water leaks. Low Battery Warning Function: Worried about your leak detector running out of power and stopping? The product has a low battery warning function. When the battery level drops below 5%, a buzzer and LED light will alert you; the LED light will flash while the buzzer sounds once every 1 minute.
