Are temporal artery thermometers accurate for adults?

Temporal thermometer readings average about the same as rectal and ear thermometer readings in some studies, but lower in others. These thermometers seem to have the most inconsistencies in how they compare to other methods.
Why is my temperature different on each temple?
At times, you can expect larger differences from temperatures taken at other body sites. This is because of two main reasons: Temporal artery temperature changes faster than a temperature taken rectally. Temporal artery temperature is not affected by the things that cause oral and underarm temperatures to be misleading ...

001) The most accurate one was chosen, and the normal range of forehead temperature in 1000 subjects detected by this method was 31.0 degrees C to 35.6 degrees C. Conclusions: Our study shows that commercially available, handheld infrared thermometers require individual validation.
Why is my forehead thermometer inconsistent?
If sweating, the temperature on the neck behind the ear lobe becomes the overriding temperature, and since this area is not quite as stable as the temporal artery, it can easily cooled be by the thermometer in taking multiple readings. ...
