1.Overview Infrared Thermometer measures the human body or an object temperature based on the infrared energy emitted by the forehead or an object (such as milk and water). You can quickly get measurement results after pointing the temperature probe to the target via this baby thermometer. 2.Structure The thermometer consists of a shell, an LCD, buttons, a beeper, an infrared temperature sensor, and a Microprocessor. 3.Operating principle The infrared temperature sensor collects infrared energy emitted by the forehead. After being focused by a lens, the energy is converted into a temperature reading by the thermopiles and the measurement circuit. 4.Intended use The Infrared Thermometer is a non-contact infrared thermometer intended to obtain the body temperature from the forehead. It may be used by medical professionals or by consumers in a home environment.
