3 Terminology
3.1 Infrared earthermometer
A temperature measuring instrument that measures the temperature of the human body using the heat radiation exchange between the ear canal and the eardrum and the detector.
3.2 Test mode
A specific working state or method of the infrared ear thermometer; in this mode, the output of the ear thermometer does not include the human body
Part temperature correction.
Note. Also known as calibration mode, it is the mode used during verification.
3.3 Laboratory error laboratoryerror
In the test mode, the difference between the infrared ear thermometer and the black body temperature.
4 Overview
Infrared ear thermometer (hereinafter referred to as ear thermometer) uses the approximate black body cavity formed by the ear canal and the eardrum to measure the human body
temperature. The measurement principle can be described by formula (1).
