Stop freezing pipes with a hi/low temperature alert sensor by Winland
Protect your home, vacation home, pool house or guest house from freezing pipes with a hi/low temperature sensor that easily installs into most existing security systems.
This environmental device monitors temperatures from -30 to +130° F and has adjustable high and low alarm set points. When the temperature reaches above or below the point you specify, the central monitoring station is contacted and you are immediately notified.
