An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
The lens of the thermometer is sensitive and reacts not only to changes in temperature but also to dirt or grease. It clogs up the lens and gives you incorrect results. The lens is quite small, so it’s easy to get dirty even when it’s not visible to the naked eye.
Temperature can vary slightly from left to right ear because of the amounts of dirt or earwax present or due to individual variations. Please note the position of the probe tip during measurement can have an influence on the results.
