Differences between measurements can also result from the following factors: The thermometer is not the same temperature as the room you are measuring in (Example: it has been in a much warmer or colder room). The thermometer is inserted into the ear canal at a different depth or angle.
How does a probe thermometer work?
Probe thermometers consist of a thin metal rod (a probe), that’s connected by a wire to a digital display.

How far under tongue should thermometer go?
Position the thermometer in the correct area, as close to the center as possible, under the tongue. The areas of the lower jaw next to the lower molars are heat pockets. Sticking the sensor or probe into this area is essential to getting the closest oral temp measurement.
Can digital thermometer be wrong?
No thermometer will provide accurate results if it’s used incorrectly. Never use a thermometer on a person that is meant for another purpose, such as a laboratory or meat thermometer. These won’t provide accurate readings.
