The Taylor Pro Digital Refrigerator and Freezer Thermometer ensures that the temperature in your appliance is cool enough to keep food fresh and safe to eat. This round thermometer can be placed in the fridge or freezer with either the attached magnet, clip or stand. It is programmed with a specific "safe" zone temperature that during power outages will record and display the amount of time the temperature was above optimal so you can monitor potential food safety concerns.
