Some Useful Information

How the No-Touch Forehead Thermometer Works
This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point, and then calculates the oral-equivalent value using a unique algorithm based on actual body temperature survey data.
About Body Temperature
Body temperature refers to the stable temperature of the inner body (also known as the core body temperature). While temperature measurements at the armpit or mouth provide surface temperature values, holding the thermometer steadily at the measurement point for approx. 10 minutes provides a temperature measurement more closely representing that of core body temperature.
Since forehead temperature measurement involves no bodily support of the thermometer, the resulting measured temperature is typically lower than that of the armpit or mouth.
However, since the forehead has blood vessels that are much less prone to vascular constriction (a natural function of body temperature adjustment), it is supposedly a better measurement area for determining core body temperature, even in a lower temperature environment. By contrast, the temperature measured at the arm or leg, for example, is not a suitable gauge of core body temperature, since such body areas are more subject to vascular constriction.
(Note that temperature measured at the forehead may still be influenced by other conditions, such as sweating, or wind from an air conditioner, etc. It is therefore advised to perform the measurement in as stable an environment as possible.)
When measuring the temperature of an infant, note that infant body temperature is generally higher than adult body temperature and easily affected by external factors. For example, body temperature tends to increase after nursing or crying.
Therefore, it is recommended to take measurements with the infant in calm and normal condition.

Some Useful Information

Temperature differences between body temperature and forehead temperature

This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point and then calculates the oral-equivalent value using a unique algorithm (forehead measurement mode) based on actual body temperature survey data.

Some Useful Information

Knowing One’s Normal Temperature
In order to make a correct judgment of suspected fever conditions, it is important to know one’s normal temperature.
Normal temperature varies with the individual and also changes depending on the time of the day. In addition, measured body temperatures may vary depending on the thermometer or the body part where you measure (see the graph “Variances in core body temperatures obtained at the forehead and mouth”). To find out one’s normal temperature, therefore, we recommend performing regular measurements under the following conditions:

• Measure with the same thermometer.
• Measure at the same area.
• Measure at the same time of day.

Variances in core body temperatures obtained at the forehead and mouth (Cases surveyed: 190, ages: 0 – 68, environment temperature: 23 ± 2°C)
