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.

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.

Instructions

1Measure forehead temperature

The field strength of the fixed radio frequency transmitter is determined by surveying the electromagnetic fieldc, and in each frequency ranged should be lower than the compliance level.

Interference may occur in the vicinity of equipment marked with the following symbols.

---|---|---|---
Note 1： At 80MHz and 800MHz, the higher frequency band formula is used.

Note 2 ：These guidelines may not be suitable for all situations. Electromagnetic propagation is affected by absorption and reflection from buildings, objects, and humans.

a  Stationary transmitters, such as base stations for wireless (cellular/cordless) telephones and terrestrial mobile radios, amateur radios, AM and FM radio broadcasts, and television broadcasts, whose field strength cannot be accurately predicted in theory. In order to assess the electromagnetic environment of fixed radio frequency transmitters, electromagnetic field surveys should be considered. If the measured field strength of the TE-79 infrared forehead thermometer is higher than the above applicable radio frequency compliance level, the TE-79 infrared forehead thermometer should be observed to verify its normal operation. If abnormal performance is observed, supplementary measures may be necessary, such as readjusting the direction or position of the infrared forehead thermometer.
