A digital thermometer is a device used to measure temperature quickly and accurately. It typically features an electronic sensor that detects temperature changes and displays the reading on a digital screen. Digital thermometers are commonly used in medical settings to check body temperature, but they can also be used for cooking, weather monitoring, and other applications. These thermometers come in various types, including oral, rectal, and ear models, each designed for specific uses. Many digital thermometers provide results in just a few seconds, making them convenient and efficient. They are often preferred over traditional mercury thermometers due to safety and ease of use.
