Braun TempleSwipe Temporal Thermometer BST200 is a thermometer for infants, children and adults that allows quick, gentle and easy temperature taking. Safe and hygienic, it works by placing it towards the temporal artery, which is directly connected to the heart, providing constant blood flow and being placed close enough to the surface of the skin to provide an accurate temperature measurement. Thanks to TempleSwipe technology, the sensor detects a multitude of infrared heat points and thus obtains a correct and precise temperature with each measurement. Simply take the temperature and the screen will light up green, yellow or red to help you interpret the measurement. The box contains : 1 thermometer, 1 protective cap, 2 x 1. 5V AAA LR03 alkaline batteries. Guaranteed 2 years.
