EAR & FOREHEAD THERMOMETER 201

ENGL

ISH

The Ear & Forehead thermometer uses infrared technology to measure 
infrared energy emitted from the forehead or eardrum and surrounding 
tissue, and then converts it into temperature value.

Normal human body temperature fluctuates throughout the day; generally, 
lowest in the morning, highest in the evening.
Different parts of human body also have different temperatures. Therefore, 
the standards of measuring oral, axillary, rectal and ear temperatures are 
different. The human body temperature is controlled and adjusted by the 
hypothalamus in the brain. As the veins flow through the hypothalamus, they 
also flow through the ear-drum in the mid ear. Thus, measuring the ear 
temperature (the temperature of the ear drum membrane) can best reflect the 
body temperature.

Normal body temperature is a range, not a fixed value.
When using an IR ear thermometer to take temperature, the normal body 
temperature range is 35.8 °C - 38.0 °C. Also, people's normal temperature 
ranges tend to decrease with their age.

However, the normal range is also different from person to person. To 
determine your and your family members' normal temperature ranges is very 
important. It can be done easily by using our Infrared Thermometer. Please 
practice to take temperatures on yourself and your healthy family members 
to determine their normal temperature ranges.

-  Please read carefully through the following information concerning safety 

and proper use. Make yourself familiar with all the functions of the equip-
ment. Be careful to keep these advice notes and if necessary pass them 
on to a third party.

-  This thermometer is intended for household use only. The use of this ther-

mometer is not intended as a substitute for physician’s consultation.

-  Don’t touch or blow the infrared sensor. A polluted infrared sensor may 

cause inaccuracy.
