How Does it Work?
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.

Body Temperature
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:
| 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
