The Physical Performance Of Infrared Thermometer

Due to the need for medical development, in many cases, the general thermometer has been unable to meet the rapid and correct temperature measurement requirements, such as stations and airports where the population density of the larger body temperature measurement. Although the current foreign temperature measurement technology are more mature, but the domestic technology in this area is still in the development stage.Infrared Thermometer

Therefore, in order to meet the needs of medical development, effectively carry out the special environment of temperature measurement, which effectively control and prevent such as SARS and the like special disease spread, need to design a temperature measurement speed, the correct rate of high temperature instrument. For the general industry with the infrared thermometer accuracy is not high enough, according to the principle of this infrared temperature measurement, through the selection of key devices, targeting system design and automatic adjustment of temperature compensation to improve the accuracy of infrared thermometer Degree, designed a kind of infrared temperature measurement circuit, for staff-intensive and large traffic occasions for rapid human body temperature measurement.Infrared Thermometer

The use of this principle made of temperature measurement instrument called infrared temperature meter. This measurement does not need to contact with the measured object, so it is non-contact measurement. Infrared temperature meter temperature range is very wide, from -50 ℃ up to higher than 3 000 ℃. In different temperature ranges, the wavelength distribution of the electromagnetic wave energy emitted by the object is different. At room temperature (0 ~ 100 ℃), the energy is mainly concentrated in the mid-infrared and far-infrared wavelengths. For different temperature range and for different measurement of the instrument, the specific design is also different.Infrared Thermometer

The infrared radiation characteristics of the human body and his surface temperature has a very close relationship, therefore, through the body's own radiation infrared energy measurement, will be able to correctly determine the body surface temperature. Infrared temperature measurement technology, the biggest advantage is the test speed, within 1 s can be tested. Because he only receives the infrared radiation emitted by the human body, there is no other physical and chemical factors on the human body, so no harm to the human body.Infrared Thermometer
