Greisinger 482757 Water Detector with External Sensor, Mains-Powered

Water leaks can cause extensive damage before they are even noticed. The Greisinger 482757 water detector provides early warning by monitoring for the presence of conductive liquids using an external sensor. When water is detected, it triggers an audible alarm, a visual LED, and a relay output, allowing you to take immediate action.
