An alcohol thermometer is a temperature-measuring device that uses dyed alcohol inside a glass tube to indicate temperature changes. It is commonly used in laboratories, environmental monitoring, and low-temperature applications because alcohol remains functional at colder ranges where mercury cannot. It is generally accurate for routine measurements, though it is not as precise as digital or infrared instruments.
