Did you know that what’s considered a fever for a 3 month old is different than that of a toddler or adult? Braun's ThermoScan 7 ear thermometer features Age Precision technology which takes the guesswork out. Easily set the age of your child (0-3 months, 3-36 months or 36 months ) and use the color-coded display to quickly interpret the reading based on your child’s age.
