The new Braun No touch + forehead thermometer is gentle enough for a sleeping baby. With its revolutionary dual technology and ultra-sensitive sensor, now you can get fast and precise temperature readings either in touch mode, by placing the thermometer on the forehead, or by holding it in front of the forehead up to 5 cm away in the no-touch mode. Silent mode is available for sleeping babies. The Forehead Thermometer measures infrared energy radiated from the skin above the eyebrow area and the surrounding tissue. Temperature readings obtained by scanning the temple area will provide the greatest accuracy. The Forehead Thermometer has been clinically tested and proven to be safe and accurate when used in accordance with its operating instruction manual.
