About Ear Thermometers

All objects radiate heat. To measure body temperature, this ear thermometer uses an infrared sensor incorporated in its probe to detect the heat radiated from the eardrum and its periphery. In general the ear canal (external auditory canal) of an infant is relatively straight. As we grow older, it takes on some curvature, as shown in Fig. 2. It is important to point the probe window of the ear thermometer toward the eardrum and its periphery inside the ear. To straighten the ear canal, gently pull on the outer ear in the direction of the rear of the head, as shown in Fig. 3. Each ear canal has a slightly different shape. Be sure to check it before measurement. And then insert the prove straight, as shown in Fig. 4.
