Infrared thermometer, also known as an ear thermometer, is an instrument that measures body temperature and 體溫計比較 of a mercury thermometer. However, the accuracy of the ear thermometer has also been questioned, so what is the measurement error of the ear thermometer gun?
Error of sampling
The accuracy of the ear thermometer is not high, and it is easy to produce sampling errors. Reason analysis: For example, there is earwax in the ear at the time of measurement, which may affect the accuracy.
The error of product design
Ear temperature gun accuracy is not high, there may also be a product to carry out the design of the error. The main analysis 耳溫槍推薦, it can be in accordance with our national safety standards only provide for the verification of the accuracy of room temperature 23 ± 2 ℃ and indoor humidity 50% ± 20%, which means that the effect outside this world has not been further verified, there may be some problems in the design process of the product structure.
The error of inaccurate operation
Ear temperature gun accuracy is not high, there is the error of inaccurate operation. Cause analysis: The use of the ear temperature gun should be very standardized, otherwise it will affect the measurement effect.
Advantages of the ear temperature gun
1, compared with the mercury thermometer, ear temperature gun the biggest advantage is convenient for students who refuse to actively cooperate with the use of small babies, the use of the time we only need to pull their baby’s ear for measurement, you can develop quickly know the body temperature of Chinese babies.
In addition, due to the fragility of mercury thermometers, coupled with the public’s concern about mercury發燒處理, so the use of mercury thermometers has been discontinued.
3, however, ear temperature gun in measuring the accuracy of body temperature research development is highly controversial in society, according to the use of infrared sensing environmental temperature reliable? There is a fixed point in the inferior optic thalamus in the deep part of the brain that can govern the constant temperature of our body, and the temperature of the inferior optic thalamus appears to rise as the earliest when fever is present, and the blood flow supplying the eardrum and the inferior optic thalamus happen to have traffic with each other, so it is most reasonable and appropriate to use the eardrum temperature to reflect the temperature change of the human body. Here we suggest that by everyone buy the national machinery note Xu, high precision, temperature measurement work range, quality assurance.
