Why Braun No Touch Thermometer?
Measurement in under 2 seconds
The innovative infrared technology allows measurement of forehead temperature in under 2 seconds. ⏱️ 2 sec
Accurate and reliable
Due to the technology, the No Touch thermometer captures the heat naturally given off by the forehead to calculate body temperature value. ⚕️
Easy to use
The No Touch thermometer is non-invasive. A measurement can be taken even while a child is sleeping. The No Touch thermometer is safer to use on a child than a rectal thermometer and is easier to use than other methods. ?
Safe and hygienic
Helps minimize spreading of germs. Safe for use on children and adults. ?
How does the Braun No Touch Thermometer work?
The No Touch thermometer measures infrared energy radiated from the skin at the center of the forehead just above the eyebrows. This captured energy is collected through the lens and converted to an oral equivalent value. The No Touch thermometer has been clinically tested and proven to be safe and accurate when used in accordance with its operating instruction manual.
Fever Guidance Color-Coded Display
Fever guidance helps you to better understand the meaning of the individual's temperature with the color indicated on the display. The color-coded screen displays GREEN for a normal temperature, YELLOW for a fever, and RED for a high fever.
| Color Range | Reading | Meaning |
|---|---|---|
| Green | >96.3 °F - 99.4 °F | Normal |
| Yellow | >99.4 °F - 101.3 °F | Fever |
| Red | >101.3 °F | High fever |
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 99.9°F (37.7 °C) or as low as 97.0°F (36.1°C). Be sure to note this unit reads up to 1.0°F (0.6°C) lower than a rectal digital measurement because it provides an oral equivalent reading.
Note: The thermometer and individual being measured should be in the same ambient temperature for at least 30 minutes to avoid impacts to measurement accuracy.
- ALWAYS hold the thermometer and the forehead steady when taking a reading.
- DO NOT move the thermometer until you hear the final beep (unless in silent mode).
- Nursing mothers should not take a temperature measurement on themselves or have their temperature measured by another individual while or immediately after nursing a baby, as nursing can affect body temperature.
- 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 the forehead before taking a measurement.
- ALWAYS take the temperature exactly as directed. Temperature results may vary if positioned in the wrong location.
Situations Recommended for Three Measurements:
In the following situations, it is recommended that three temperature measurements from the same location be taken, and the highest measurement of the three be used as the reading:
- Newborn infants in the first 100 days since birth.
- 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:
- Prior to measuring, remove any dirt or sweat from the forehead with a dry cloth.
- Avoid any cooling or warming cloths on the forehead for at least 30 minutes prior to measurement.
- Remove blankets and pillows away from the head and face prior to measurement.
- DO NOT take temperature measurements over scar tissue, open sores, or abrasions.
- ALWAYS store the thermometer in a dry, clean environment. DO NOT store in areas with sharp objects that could scratch the sensor. Dirt, debris, and scratches will impact the accuracy of temperature readings.
