How high is the accuracy to be a medical-grade infrared thermometer?

The outbreak of the New Coronary Pneumonia epidemic has made people pay more attention to public safety. In this epidemic prevention and control work, the most widely used are infrared forehead thermometer and infrared screening instrument, but after using infrared thermometer, many people feedback that the temperature measurement is not accurate.

In the end, how accurate is an infrared thermometer that is a qualified medical-grade infrared thermometer that can be used as medical diagnostic data?

Strictly divided, medical grade infrared thermometers have the highest accuracy requirements, and the accuracy needs to be between 0.1 and 0.2 degrees.High-precision infrared ear thermometers can meet the standards of medical-grade temperature measurement, but in order to avoid cross infection, hospitals use ears Disposable sheath is needed when warming the gun; Followed by consumer grade, accuracy of about 0.5 can meet our daily temperature measurement needs, such as Baoma used to measure the temperature of bath water and so on.

At present, most handheld infrared forehead temperature guns are priced between one hundred yuan and one thousand yuan, and the accuracy is mostly around 0.3 degrees. They are consumer-grade infrared thermometers; the industrial grade is the lowest, and the general maximum allowable error is ±1℃ Above, and the distance measurement is far away.
