Why is there temperature inaccuracy?

Eliminate interference factors before temperature measurement

The infrared forehead temperature gun belongs to a non-contact thermometer, which uses the relationship between the thermal radiation of the object and the temperature of the object to measure the temperature, which is convenient and simple to use.

Many people will report that the forehead temperature gun will occasionally be inaccurate, which means that you have used it improperly, do not master the measurement principles and methods, and the measured temperature results will have distorted errors.

First of all, accurate temperature measurement needs to eliminate interference factors. The air, water vapor, and other obstructions in the measurement environment will also change the radiation curve of the object, resulting in inaccurate temperature measurement. Ensure that the optical system part of the thermometer is clean and free from dust, water vapor, etc., and the tester's forehead and ear canal are free of sweat, hair, dust, hats and other debris. At the same time, the measurement of body temperature needs to be indoors in a windless environment. It must also be ensured that the use of the instrument cannot withstand the temperature difference and the normal working environment of the instrument. In the case of sunny weather and cold weather, the temperature measured by the thermometer is not referenced It is abnormal work.

In essence, the mode and measurement unit of the thermometer and the forehead must be adjusted to the forehead temperature mode. You cannot choose the wrong one when selecting the mode.

How to ensure accurate temperature measurement? Avoid strenuous exercise 20-30 minutes before body temperature measurement, eat, drink cold or hot water, do not apply hot or cold compresses, maintain emotional stability, and do not be nervous.
