???????? In fact, to measure body emperature by infrared requires not only require high precision instrument itself, such as accurate to 0. 1 ℃, but also involves the body's radiation characteristics, physiological characteristics and environmental impacts. The so-called radiation, can be popularly understood as an object launched from outside ,I it related to the object material and the surface situation.

??????? In the measured temperature, we see that the tester is to be tested against the infrared thermometer or ear cavity Yintang to get data, which is closely related to human physical characteristics. You know, ?the body temperature is a difference in different parts of the body Typically, the peripheral temperature away from the heart is lower, face and hands is about 32 ℃. ?In contrast, the best parts of measuring the temperature is ear cavity, largely because of the confounding factors that can be avoided. Importantly, our core body temperature is mainly the brain, heart and liver temperature, adjust the tympanic membrane and hypothalamus share a common blood circulation. That is, measuring tympanic temperature is more close to the body's true temperature. Of course, in order to avoid contact with the infection can be accompanied by one soft plastic diaphragm. In use, many people rush to measure the body temperature of the external ear or ear parietal, are not properly the measured temperature value is also inaccurate.
??????? Now, "influenza," the threats to mankind, Therefore, people should be early prevention, in which infrared thermometer is still a good idea to survey.
