An **Infrared Thermometer**, also known as a non-contact thermometer, is a modern and hygienic device used to measure body temperature without physical contact. It works by detecting the infrared energy emitted by the body, converting it into a temperature reading that is displayed on a digital screen, often within seconds. This non-invasive method makes it particularly useful for quickly screening multiple individuals, such as in schools, airports, or healthcare settings, and for taking temperatures of restless children or sleeping infants without disturbance. Many models offer forehead or ear measurement options and may include features like fever alerts. The infrared thermometer's ability to provide accurate readings from a distance minimizes the risk of cross-contamination, making it a highly convenient and safe tool for rapid temperature assessment in various environments.
