Set of three 2.0 detectors

Get a set of three 2.0 detectors, which detect both water and freezing conditions. Each detectors sends an alert as soon as water is detected at any of its four contact points or the temperature drops below 41°F (5°C). Install them anywhere frozen water could cause damage or in areas prone to leaks. Buying a set of three saves you over 5% compared to purchasing three sensors individually.
