Where should the infrared thermometer measure? The wrist or the forehead?

Mar 01, 2021

In daily life, it is often seen that infrared thermometers are used to measure human body temperature, but people measure different parts, some are on the wrist, and some are on the forehead. So, is it accurate to measure the forehead or the wrist?


In fact, there is not much difference between these two places. It may be a habit of movement. The temperature measured on the forehead and wrist has an error of about 0.2, which will not have much effect.


We can pay attention to the following issues in the process of use:


1) Pull out the hair, avoid covering, wipe off the sweat, and check whether the infrared forehead thermometer is in the body temperature mode. Please refer to the product manual for the method of entering the body temperature mode.

2) When measuring, aim the infrared forehead thermometer at the center of the forehead, generally the distance is 1-3cm, for some products, the distance is 3-5cm, and the specific product instructions shall prevail. At the same time, note that the infrared forehead thermometer cannot be moved away from the temperature measurement position before the measurement is completed.

3) When the measured person comes from a place where the temperature of the measurement environment is very different, he should stay in the measurement environment for more than 5 minutes, and measure after the temperature is consistent with the environment, otherwise the measurement result will be affected.

4) The body temperature of different parts of normal people is different, and the body surface temperature is about 36.3-37.2℃. If the measurement result exceeds the normal body surface temperature range, it is recommended to measure more than 3 times, the interval between each measurement is 3-5 seconds, whichever is the most displayed data.
