About ear thermometers
The tympanic thermometer, or simply, the ear thermometer, measures a persons temperature by infrared light. One only has to put it in the ear and press a button to see the temperature on the display. The measurements are very exact, however not as exact as with a rectal thermometer. Up to half a degree Fahrenheit is how much a measurement can differ between the two. This is why it is not recommended to use an ear thermometer on an infant just a couple of months old, cause half a degree in this case is a lot. However, for everyone that is not an infant, the ear thermometer is a brilliant invention that makes very accurate readings of a persons temperature, instantly and without fuss. They may be used on adults and children and even toddlers, but again, avoid using them on an infant that's only a few months old.
Another big advantage is that germs are not as easily transmitted as with other thermometers.
