3、Body temperature and measurement principle
All objects in nature whose temperature is higher than absolute zero (-273°C) will
radiate infrared rays, and the energy of the radiated infrared rays is proportional to
the temperature. Using this relationship, the temperature of the object can be calculated
by measuring the infrared intensity of the object.
This product uses an infrared sensor
to aim at the forehead to measure human body temperature. Measuring the human body
temperature through the forehead can accurately reflect the core temperature of the human
body.
Tips：The normal body temperature of the human body is not constant. There are
differences in the body temperature of different parts of the human body in the morning
and evening and between men and women, and there is a relatively stable range. It is
normal to measure the same part after a few minutes, and there may be a few tenths of
a degree Celsius change;
Especially the child's temperature control function has not
been fully developed, and the temperature changes will be more frequent. It is
recommended to measure several times and take the highest value. If you find that the
child's temperature is abnormal, you should seek medical attention in time.
Notes：
1: The above clinical accuracy data is the result of comparison of the clinical test
between this product and the CRW-23 glass thermometer produced by Jiangsu Chenyu
Medical Equipment Co., Ltd.
2: The clinical accuracy or clinical deviation of the infrared forehead
thermometer has been clinically verified, and its safety and effectiveness are
in compliance with relevant national regulations. The claimed performance
verification method of the product can be obtained by contacting the company's
customer service department.
4、Product scope/structure composition
This product is composed of a plastic shell, a sensor, an LED display, an
alkaline battery, a control circuit and a buzzer. It is suitable for displaying
the temperature of the human body by measuring the thermal radiation of the human
forehead.
