The three major classifications of Termômetros infravermelhos médicos are based on their main purpose and precision. Infrared thermometers can be roughly divided into medical equipment grade Termômetro infravermelhos, consumer grade Termômetro infravermelhos and industrial production grade Termômetro infravermelhos.

Strictly up the distinction, medical equipment-grade Termômetro infravermelhos have the highest precision requirements, and the precision must be between 0.1 and 0.2 degrees. High-precision infrared ear thermometers can meet the specifications of medical equipment-level temperature measurement. In order to prevent infection, A disposable sheath must be provided when the ear thermometer is used in the outpatient department of the hospital; secondly, the precision of 0.5 can meet everyone's usual temperature measurement requirements, such as the temperature measurement of the bath water by the mother.

1. O desenvolvimento de termômetros infravermelhos médicos no mercado

At this stage, most portable Termômetros infravermelhos testa from medical thermometer manufacturers are currently on the market. The price is between US$15 and US$150 and the precision is around 0.3 degrees. They belong to consumer-grade Termômetro infravermelhos. The industrial production grade is the least, generally the larger allowable deviation is above ±1℃, and the laser distance measurement is far away.

The difference between various popular Termômetros infravermelhos médicos. In fact, whether it is medical equipment or industrial Termômetro infravermelhos, the basic principle of their application is to accept infrared waves from the body, only the object distance is adjusted differently, and all that is accurately measured is the ambient temperature.

Toda a temperatura normal da testa do corpo é 2-3 ℃ mais baixa do que a temperatura da axila, e a temperatura da testa é afetada extremamente pelo ambiente. É usado apenas como referência para exames básicos e não pode ser usado como base para diagnóstico médico. Portanto, medicina médica e clínica referem-se à temperatura da axila como medição de temperatura médica.

Além disso, a temperatura das orelhas, da cabeça e do pescoço será mais estável do que a temperatura da testa e será menos afetada pelo ambiente natural.

The long-wave infrared emissivity of body skin is 0.98 (default setting of Termômetro infravermelho is 0.95), so the accurate measurement result is around 34-35℃. All infrared products including (infrared thermal imaging camera) can be adjusted according to the change emissivity of 0.8 Errors to prevent abnormal body temperature caused by laymen's application. The industrial production-grade Termômetro infravermelho provides more true feedback of the temperature measurement status, and the information displayed is the temperature that is specifically tested.

In the past, a large number of Termômetro infravermelhos were used for temperature measurement in industrial production. Later, due to market demand, the basic development trend of industrial production-grade Termômetro infravermelhos showed that the detection range was smaller, the precision was higher, and the temperature was more suitable. A medical Termômetro infravermelho for measuring the temperature of the human body. During the 2003 "Fight against SARS" period, most of the applications used were industrial production-grade Termômetro infravermelhos.

Since the price of an industrial-grade portable Termômetro infravermelho at that time was generally around US$150, you could buy it for as little as US$90. The medical thermometers available on the sales market not only have a smaller supply of goods, but also have a much higher price.

In recent years, with the development of technology, Termômetro infravermelhos have made great achievements in precision, volume and cost reduction. Only portable Termômetros infravermelhos médicos and consumer-grade Termômetro infravermelhos are enough to get rid of the sales market dominance of industrial production-grade Termômetro infravermelhos.

In the epidemic, Termômetros infravermelhos médicos and consumer-grade Termômetro infravermelhos are widely used in public places such as hospital outpatient clinics, airports and subway stations, farmer's markets, supermarkets, and residential communities. Industrial production-grade Termômetro infravermelhos with relatively low precision are also withdrawn from the stage of epidemic prevention and control.
