Comfortable Infrared Ear Thermometer Celsius / Fahrenheit Mode Selectable

Product description

The ear thermometer is a non-contact telemetry (though maybe less than one centimeter) temperature measuring

instrument. It uses the infrared spectrum of the eardrum (equivalent to the hypothalamus) to determine the body

temperature. According to the black body radiation theory, different The infrared spectrum generated by objects

with different temperatures is also different. It is displayed by using a thermopile infrared detector that can be

accurate to 0.1 ° C and then converting the readings by a microcomputer.

Human thermostatic position

There is a place in the deep part of the brain called the hypothalamus, which contains a "set-point" structure that

governs the body's temperature. The hypothalamus is also the central point of the body temperature. When the human

body has a fever, it is the result of "spot-pointing" the increase in the number of inflammatory chemicals

circulating in the bloodstream. The hypothalamus is the earliest place where the body temperature rises. It happens

to have traffic, so the eardrum temperature is the best way to reflect the temperature of the human body.
Appropriately, the eardrum is also the earliest place to detect whether the body has a fever.

The allowable error of the ear thermometer itself is usually ± 0.2 ° C within the range of 36-39 ° C, and ± 0.3

° C above 39 ° C and below 36 ° C. When used, incorrect use will also cause additional errors. Such as a large

amount of ear wax in the ear canal, will bring errors. When the ear thermometer plugs the ear hole during

measurement, the temperature field in the ear hole will change, and the value will change if the measurement time

is too long. When repeating multiple measurements, if the measurement interval is not appropriate, each reading

will be different.

Precautions

(1) It is best to use a new "outer film cover" every time you use it. There is not enough "outer film cover" to use

plastic wrap, but it is more troublesome.
(2) The deeper the tip, the better, but do not cause discomfort.
(3) When testing children, it is best to gently pull the ears back and upward (straighten the ear canal).
(4) It is best to measure both ears, or even measure one ear three times, and take the highest value (because there

may be an error of 0.1 ℃ ～ 0.3 ℃ on both sides).
(5) Just expose to the sun for too long or exercise, avoid measurement, otherwise the measured value may be higher

than the actual temperature.
