The three major classifications of Medizinische Infrarot-Thermometer are based on their main purpose and precision. Infrared thermometers can be roughly divided into medical equipment grade Infrarot-Thermometers, consumer grade Infrarot-Thermometers and industrial production grade Infrarot-Thermometers.

Strictly up the distinction, medical equipment-grade Infrarot-Thermometers 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. Die Entwicklung von medizinischen Infrarot thermometern auf dem Markt

At this stage, most portable Infrarot-Stirn thermometer 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 Infrarot-Thermometers. 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 Medizinische Infrarot-Thermometer. In fact, whether it is medical equipment or industrial Infrarot-Thermometers, 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.

Alle normalen Körper stirn temperatur ist 2-3 ° C niedriger als die Achsel temperatur, und die Stirn temperatur wird stark von der Umgebung beeinflusst. Es wird nur als Referenz für Basis untersuchungen verwendet und kann nicht als Grundlage für die medizinische Diagnose verwendet werden. Daher beziehen sich die medizinische und klinische Medizin auf die Achsel temperatur als medizinische Temperatur messung.

Darüber hinaus ist die Temperatur der Ohren, des Kopfes und des Halses stabiler als die Temperatur der Stirn und wird weniger von der natürlichen Umgebung beeinflusst.

2. industrielle und medizinische Infrarot-Thermometer

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

Since the price of an industrial-grade portable Infrarot-Thermometer 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, Infrarot-Thermometers have made great achievements in precision, volume and cost reduction. Only portable Medizinische Infrarot-Thermometer and consumer-grade Infrarot-Thermometers are enough to get rid of the sales market dominance of industrial production-grade Infrarot-Thermometers.

In the epidemic, Medizinische Infrarot-Thermometer and consumer-grade Infrarot-Thermometers 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 Infrarot-Thermometers with relatively low precision are also withdrawn from the stage of epidemic prevention and control.
