This thermometer is based on R.A.T.E™ (Rapid, Accurate, Temperature,
Establishment) technology. The accurate measurement is obtained by
using a unique probe, which measures the heat flow from the blood
vessels to the skin and converts it to body temperature.
How Does it Work?
What is “normal” body temperature? “Normal” body temperature
varies from person to person and changes according to time of day and
body location. Hot or cold baths, physical exercise, smoking and
drinking hot or cold drinks may change body temperature by one degree
or more.
The following table shows the temperature ranges:
Body Temperature
What is fever ? Average normal temperature ranges
Forehead Over 100.0°F / 37.8°C 97.0°F - 100.0°F / 36.1°C – 37.8°C
Rectal* Over 100.4°F / 38°C 97.3°F - 100.4°F / 36.3°C – 38°C
Oral * Over 100.0°F / 37.8°C 97.0°F - 100.0°F / 36.1°C – 37.8°C
Underarm* Over 99.0°F / 37.2°C 95.4°F - 99.0°F / 35.2°C – 37.2°C
* Fever definitions according to the American Medical Association
The thermometer is designed to precisely measure the temperature
of the forehead between the eye socket and the hairline. It is
important to know that the thermal characteristics of each
measurement body location (temple, underarm, oral or rectal) are
unique. The variance in temperature measurement in different
