EAR & FOREHEAD THERMOMETER 301
ENGLISH
1 INTRODUCTION
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.
The Ear and Forehead Thermometer can also be used for measuring the
room temperature and the temperture of food and fluids.
2 ABOUT BODY TEMPERATURE
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 - 37.6 °C. Also, people's normal temperature
ranges tend to decrease with their age.
IMPORTANT NOTE
• It is important to determine your and your family members' normal
temperature ranges and write them down.
• Practice to take temperatures on yourself and your healthy family
members to determine their normal temperature ranges.
• It is important to clean your thermometer before the first time of use
and after each application, otherwise the result may be incorrect.
• After a shower or exercise, the body temperature will rise. Take a rest
before taking temperature.
