By selecting Braun ThermoScan® 7, you are choosing the no.1 thermometer brand among doctors. Thanks to its patented pre-warmed tip, Braun ThermoScan® ear thermometers are already regarded as a benchmark for accuracy, and are widely used and endorsed by doctors around Europe. The tip on other thermometers can cool the area where the reading is taken, which can lead to inaccurate readings. The tip on the ThermoScan® is warmed before use, to ensure professional accuracy.
