Why Braun No touch + forehead?

Measurement in under 2 seconds
The innovative infrared technology allows measurement of forehead temperature in under 2 seconds whether you use the forehead or no touch option.
Accurate and reliable
Due to the unique technology, the No touch + forehead thermometer captures the heat naturally given off by the forehead to calculate body temperature value. Get the same professional accuracy whether touching your forehead or holding up to 2.5 cm (1 inch) away.
Easy to use
The No touch + forehead thermometer is non-invasive. A measurement can be taken even while a child is sleeping.
The No touch + forehead thermometer is safer to use on a child than a rectal thermometer and is easier to use than other methods.
Safe and hygienic
The no-touch option helps minimize the spreading of germs. Completely safe for use on children and adults.

How does Braun No touch + forehead work?

The No touch + forehead thermometer measures infrared energy radiated from the skin at the center. This captured energy is collected through the lens and
converted to an oral equivalent value.
The No touch + forehead thermometer has been clinically tested and proven to be safe and accurate when used in accordance with its operating instruction manual.

1.  A traditional forehead product without any optical system to capture radiated heat.

AgeSmart ™ color-coded display

Clinical research shows the definition of fever changes as newborns grow into infants, infants grow into children and children grow into adults.1
Select the appropriate age setting, take a temperature, and the display will glow green, yellow, or red to indicate whether the temperature is in a normal, moderate fever, or high fever range, respectively.
The device is only intended for the measurement of human body temperature. It is not intended to diagnose or monitor a serious medical condition or disease.
The device also has a food/bath mode.

Temperature taking hints

It is important to know each individual’s normal temperature when they are well. This is the only way to accurately diagnose a fever. Take multiple readings when
healthy to determine normal temperature.
A child’s normal temperature can be as high as 37.7 °C (99.9 °F) or as low as 36.1 °C (97.0 °F). Be sure to note this unit reads 0.6 °C (1.0 °F) lower than a rectal
digital measurement.
The thermometer needs to acclimate to the room temperature for 10 minutes before taking a measurement.
The individual being measured should be indoors for 30 minutes before taking a measurement. External temperature can impact skin temperature.
If the individual is inside but in a room that is more than a few degrees warmer or cooler than the room the thermometer is in, it will impact the accuracy of the
reading.
ALWAYS hold the thermometer and the forehead steady when taking a reading.
DO NOT move the thermometer until you hear the final beep. DO NOT take a measurement while or immediately after nursing a baby.
Individuals should not drink, eat, or be physically active before/while taking the measurement.
Remove hats and wait 10 minutes before taking a measurement.
Before taking a measurement, remove dirt or hair from the forehead area. Wait 10 minutes after cleaning before taking measurement.
ALWAYS take the temperature exactly as directed. Temperature results may vary if positioned in the wrong location.
For individuals measuring their own temperature, it is recommended to use the “forehead” option instead of “no touch.”
In the following situations it is recommended that three temperatures in the same location be taken and the highest one taken as the reading:

• Newborn infants in the first 100 days.
• Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical.
• When the user is learning how to use the thermometer for the first time until he/ she has familiarized himself/herself with the instrument and obtains consistent readings.

General precautions:

• Remove any sweat prior to measuring with a dry cloth.
• Avoid any cooling or warming cloths on the forehead for at least 30 minutes prior to measurement.
• DO NOT take temperature measurements over scar tissue, open sores, or abrasions.
• Keep the measurement sensor and lens clean. Avoid directly touching the sensor or lens.
• ALWAYS store the thermometer with the protective cap in place to prevent dirt and scratches from damaging the device.
• Make sure to remove the protective cap before taking a measurement and to put the cap back on after using the thermometer.
