In nature, any movements higher than the absolute zero (-273 degree C) exist in motion of molecular and atomic irregularities. In this process, the objects are constantly releasing radiation energy outward. The size of the radiation energy is closely related to the temperature on the surface of the object. For example: the normal temperature of the human body is between 36 and 37 degree C, and the radiation energy is infrared with a wavelength of 9 ~ 13 μm. The temperature measurement principle of infrared thermometer is to detect the infrared wavelengths of the specific parts of the human body and transform into temperature reading through electronic circuits.

• Place the thermometer in the measurement environment for at least 15 to 20 minutes to adapt it to the temperature of the current environment.
• When measuring, just hold the handle of the infrared thermometer, then 3-5 cm away from the part to be measured (such as forehead, armpit), and then press the button with your finger.
