Infrared thermometer is a measurement tool that USES the principle of radiation to measure the body temperature. The infrared sensor it USES only absorbs the infrared radiation of human body and does not emit any rays to the outside world. It senses the body temperature through non-contact methods. The infrared thermal radiation of the human body is focused on the detector, and the detector converts the radiated power into an electrical signal, which can be displayed in units of temperature after the ambient temperature is compensated. After starting the machine, just point the probe to the center of the front forehead -- above the brow and keep it vertical. The measuring area should not be blocked by hair. If there is sweat, wipe it off, distance from the forehead is recommended to be about 3-5cm. Press the measurement button and the measurement data can be obtained in a few seconds. Ningbo Younker non-contact infrared thermometer is relatively safe and accurate, suitable for the elderly, children, hospitals, families, and public places to use.
