AirShield Leak Detector Flex: stay ahead of water damage
The AirShield Leak Detector Flex is a compact wireless water detector that raises an instant alarm as soon as it detects water. Ideal next to a washing machine, dishwasher, boiler room or under a sink, exactly where a leak can cause major damage.
This Flex version (Dahua DHI-ARD912-W2(868D)) has adjustable sensitivity and can be placed on the floor or on the wall, useful in awkward spots. With a splash-proof IPX5 housing and two-way communication on 868 MHz, the signal is stable and secure.
