Upgrade design: Two probes on the back detect water leaking to the ground; one probe on the front detects drips from pipes or taps. This advanced configuration helps detect water leaks quickly and effectively. High sensitivity: Upon contact with water, liquid, or even minimal moisture, the device emits a loud 90dB alarm. The alarm continues until the probe is dried or the battery is depleted, providing an effective alert for water leaks or spills. Application: Ideal for areas prone to water accumulation. Its compact size allows easy placement near bathrooms, kitchens, basements, garages, boats, or water pipes. Helps provide early warning to protect property from water damage. Easy to use: No wiring, buttons, or programming required. Can be wall-mounted or placed on a flat surface. Simply remove the cover and install the battery. If the alarm fails to sound, replace the battery.
