Non-contact thermometers are devices used to measure body temperature without physical contact. They work by detecting infrared radiation emitted from the skin, providing quick and accurate readings. These thermometers are commonly used in medical settings, schools, and public places to screen for fever, especially during health crises like the COVID-19 pandemic. These thermometers are easy to use and often feature a digital display for clear readings. They are particularly beneficial for measuring the temperature of children or individuals who may be uncomfortable with traditional thermometers. Non-contact thermometers are also useful for measuring the temperature of surfaces and objects in various environments.
