Proper storage temperatures of meats, dairy and produce are very important. An appliance thermometer helps ensure ideal temperatures are held promoting less spoliage. The Taylor Digital Fridge/Freezer Thermometer has an extra-large LCD readout with the min/max temperatures recorded so you can easily monitor temperature changes and make adjustments to your appliance as necessary. If the refrigerator/freezer is too warm, food may spoil; if it is too cold, electricity is getting overused. For easy reference, Safe Zones are printed directly on the thermometer body. The thermometer has a convenient clip and removeable suction cup for placement in an easily viewable spot in your appliances. Thermometer reads in both Fahrenheit and Celsius. Also great for wine fridges, cellars, deep freezers, etc.
