HOW THE LIFESOURCE EAR THERMOMETER WORKS
The LifeSource Ear Thermometer utilizes infrared thermo scanning principles to
scan the temperature of the human eardrum. The eardrum is located beneath the
human body’s surface and not easily influenced by the environment’s changing
temperature.
The LifeSource Ear Thermometer is faster, safer and easier to use. Measurements
can even be taken while your child is sleeping. For adults, the LifeSource Ear
Thermometer offers fast, comfortable, accurate readings in seconds.
Why the ear?
Research indicates that the ear is an ideal site for taking body temperature. The
eardrum shares blood vessels with the hypothalamus, the part of the brain that
controls the body temperature. Therefore, the ear is an accurate indicator of internal
body temperature. An ear temperature, unlike an oral temperature, is unaf fected by
factors such as talking, eating or drinking.
We recommend that you practice with the LifeSource Ear Thermometer on yourself
and family members when you are healthy . This way you know how the thermometer
works and can feel more confident of the measurements you take when a family
member is ill.
