Appliance thermometers come in several types and style, and vary in level of technology and price.

Refrigerator/Freezer Thermometers

For safety, it is important to verify the temperature of refrigerators and freezers. Refrigerators should maintain a temperature no higher than 40F. Frozen food will hold its top quality for the longest possible time when the freezer maintains 0 ^OF.

An appliance thermometer can be kept in the refrigerator and freezer to monitor the temperature. This can be critical in the event of power outage. When the power goes back on, if the refrigerator is 40 ^OF or colder, and the freezer is still colder than 40 ^OF, the food is safe.

These bimetallic-coil thermometers are specially designed to provide accuracy at cold temperatures.

Oven Thermometers

An oven thermometer can be left in the oven to verify that the oven is heating to the desired temperature.

These bimetallic-coil thermometers can measure temperatures from 100 to 600 ^OF.
