                          Clinical human body infrared thermometer


                          The infrared thermometer consists of optical system, photoelectric detector, signal amplifier, signal processing, display output and other parts. The optical system gathers the infrared radiation energy of the target in its field of view. The size of the field of view is determined by the optical components of the thermometer and its position. The infrared energy is focused on the photodetector and transformed into the corresponding electrical signal. The signal is transformed into the temperature value of the target after being corrected by the amplifier and signal processing circuit according to the algorithm of the instrument internal treatment and the target emissivity.


                          The principle of infrared thermometer is to change the radiation energy of the infrared emitted by the measured object into electrical signal. The size of infrared radiation energy is related to the temperature of the object itself. The temperature of the object can be determined according to the size of the converted electrical signal. All objects above absolute zero will radiate infrared rays by themselves. The function of infrared thermometer is to collect the infrared rays emitted by objects, which will not emit any harmful radiation at all, so it is completely harmless to human body. Some people misunderstand that it is the infrared thermometer that emits rays to the human body to produce readings, which is wrong.

                          Blackbody is an ideal radiator. It absorbs the radiation energy of all wavelengths without reflection and transmission of energy. Its surface emissivity is 1. However, the actual objects in nature are almost not blackbody. In order to understand and obtain the distribution law of infrared radiation, we must choose the appropriate model in the theoretical research. This is the quantized oscillator model of body cavity radiation proposed by Planck. Thus, the law of Planck blackbody radiation is derived, that is, the spectral radiance of blackbody in terms of wavelength, which is all infrared radiation The starting point of the theory is called the blackbody radiation law. In addition to the radiation wavelength and the temperature of the object, the radiation amount of all real objects is related to the material type, preparation method, thermal process, surface state and environmental conditions of the object. Therefore, in order to make the blackbody radiation law applicable to all real objects, it is necessary to introduce a ratio coefficient, i.e. emissivity, which is related to the material properties and surface states. The coefficient represents the closeness of the actual object's thermal radiation to the blackbody radiation, and its value is between zero and a value less than 1. According to the radiation law, as long as we know the emissivity of materials, we know the infrared radiation characteristics of any object. The main factors that affect the emissivity are material type, surface roughness, physical and chemical structure and material thickness. The emissivity of infrared thermometer is usually adjusted at 0.95 to measure the temperature of human body.

                          The infrared thermometer used to measure human body temperature is called human body infrared thermometer. However, it must be clarified that there is no special medical or industrial infrared thermometers, because the manufacturing principles of infrared thermometers are the same. There are only high precision, high distance coefficient ratio, high performance infrared thermometer and low precision, low distance coefficient ratio and low performance infrared thermometer. As long as the emissivity of the infrared thermometer is set at 0.95 (the emissivity of human skin is generally this value, even if there is a difference, the impact is only within 0.3 degrees), it is in line with the requirements of human body temperature measurement.


                          For example: all brands of cars can run 40 yards, and high-end cars may reach 200 yards, but there is no distinction between a car that runs 40 yards and a car that runs 200 yards, only a car with high or low performance.


                          1. Non - contact, do not touch each other when measuring the human body temperature, avoid the risk of infection and ensure safety


                          2. Fast temperature measurement, accurate reading, suitable for rapid screening of large numbers of people

                          3. No need to enter the ear canal of the other side, no need to replace the earmuff, clean and sanitary


                          4. Laser positioning, accurate measurement of the temperature of the target area, can measure the temperature of forehead, armpit, body surface and other places


                          5. Temperature limit can be set, when the limit temperature is exceeded, an audible alarm will be given to accurately check the abnormal body temperature in the crowd


                          6. Infrared temperature measurement, no harm to human body
