You Searched For: Liquid Crystal Thermometers
Liquid crystal thermometers contain heat-sensitive strips that change color to indicate temperature changes. These thermometers are accurate and easy to read, as well as simple to place and remove. They can be used to observe how heat flows, and in medical applications they may be used to read body temperature through placement on the forehead. They are safer alternatives to mercury-in-glass thermometers, but do not always give exact results. Liquid crystal thermometers are also commonly used in aquariums, homebrewing, and in mood rings.
