Age Precision Technology for age adjustable fever guidance which completely takes the guesswork out of interpreting child’s temperature. AgeSmart [tm]' is new technology for Braun Ear Thermometers. Available on the new ThermoScan7 Braun IRT6520 model only. Many parents are unaware that the definition of fever changes with a child’s the age - what may be a fever for a 3 month old, may not be considered a fever for a 36 month old. With the Braun ThermoScan 7, you select the child's age before taking their temperature. The Thermometer will then instantly interpret the temperature for you, showing green for no temperature, yellow for a moderate fever, red for a high fever depending on the age selected. Patented pre-warmed tip ensures accuracy. Fast, Gentle and easy to use. Front Panel display with night light. Stores the last 9 temperature readings!
