Non-contact infrared radiation thermometers are divided into industrial and medical types. To measure human body temperature, medical infrared thermometers, infrared ear thermometers, and infrared body surface temperature detectors should be used because they have narrow measurement ranges, high resolution, and small errors. . In contrast, industrial infrared thermometers have a wide measurement range, low resolution, and large errors. However, many anti-SARS checkpoints still use industrial infrared thermometers to measure human body temperature. Therefore, it can only serve as a preliminary screening, and medical thermometers must be used to identify and exclude suspected fever subjects.

Experts also revealed that a measurement standard for temperature measuring instruments is currently being revised. The measurement standard will stipulate the maximum measurement error of the instrument and other factors. At the same time, scientific and technical personnel of the China Institute of Metrology are working overtime to produce the infrared thermometer calibration device recently developed by the institute. They plan to equip 50 ports with this device. This device not only fills the gap in my country's demand for infrared radiation thermometers. The field calibration device is blank, and the infrared radiation thermometer has a crosshair.
