Thermometers are used in roadways in cold weather climates to help determine if icing conditions exist. Indoors, thermistors are used in climate control systems such as air conditioners, freezers, heaters, refrigerators, and water heaters. [56] Galileo thermometers are used to measure indoor air temperature, due to their limited measurement range.
Always refrigerate perishable food within 2 hours—1 hour when the temperature is above 90°F (32.2°C). Check the temperature of your refrigerator and freezer with an appliance thermometer. The refrigerator should be at 40°F (4.4°C) or below and the freezer at 0°F (-17.7°C) or below. [27]
Food storage in refrigerators may not be safe unless there is close adherence to temperature guidelines. In general the temperature should be maintained at 4 °C (39 °F) or below but never below 1 °C (34 °F). [8] Safe storage times vary from food to food and may depend on how the food has been treated prior to being placed in the refrigerator.
A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
A medical mercury-in-glass maximum thermometer showing the temperature of 38.7 °C (101.7 °F). One special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion.
