The three major classifications of Thermomètres infrarouges médicaux are based on their main purpose and precision. Infrared thermometers can be roughly divided into medical equipment grade Thermomètre infrarouges, consumer grade Thermomètre infrarouges and industrial production grade Thermomètre infrarouges.

Strictly up the distinction, medical equipment-grade Thermomètre infrarouges 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. le développement de thermomètres infrarouges médicaux sur le marché

At this stage, most portable Thermomètres frontaux infrarouges 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 Thermomètre infrarouges. 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 Thermomètres infrarouges médicaux. In fact, whether it is medical equipment or industrial Thermomètre infrarouges, 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.

Toute la température normale de front de corps est 2-3 ℃ inférieure à la température d'aisselle, et la température de front est considérablement affectée par l'environnement. Il est uniquement utilisé comme référence pour les examens de base et ne peut pas être utilisé comme base pour le diagnostic médical. Par conséquent, la médecine médicale et clinique se réfère à la température des aisselles comme mesure de la température médicale.

De plus, la température des oreilles, de la tête et du cou sera plus stable que la température du front et sera moins affectée par l'environnement naturel.

2. thermomètres infrarouges industriels et médicaux

The long-wave infrared emissivity of body skin is 0.98 (default setting of Thermomètre infrarouge 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 Thermomètre infrarouge 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 Thermomètre infrarouges were used for temperature measurement in industrial production. Later, due to market demand, the basic development trend of industrial production-grade Thermomètre infrarouges showed that the detection range was smaller, the precision was higher, and the temperature was more suitable. A medical Thermomètre infrarouge for measuring the temperature of the human body. During the 2003 "Fight against SARS" period, most of the applications used were industrial production-grade Thermomètre infrarouges.

Since the price of an industrial-grade portable Thermomètre infrarouge 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, Thermomètre infrarouges have made great achievements in precision, volume and cost reduction. Only portable Thermomètres infrarouges médicaux and consumer-grade Thermomètre infrarouges are enough to get rid of the sales market dominance of industrial production-grade Thermomètre infrarouges.

In the epidemic, Thermomètres infrarouges médicaux and consumer-grade Thermomètre infrarouges 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 Thermomètre infrarouges with relatively low precision are also withdrawn from the stage of epidemic prevention and control.
