Product Description: Name: Baby Forehead Thermometer Type: Forehead temperature stickers Material: PET LCD Size: 9 * 1.6cm / 3.54 "* 0.63" For the crowd: infants and adults Function: measure human forehead temperature Measuring temperature: 35 ℃ -40 ℃ / 95 ° F-104 ° F Temperature measurement accuracy: ± 0.5 ℃ ♦ Reminder: This liquid crystal thermometer displays a temperature index based on the heating temperature. Under normal circumstances, the temperature of the forehead of the human body will be 0.5 degrees Celsius lower than the normal body temperature, but because the weather is different in each place and the environment is different, the temperature of the forehead of the human body will also be different. Therefore, users must use it at normal room temperature. In addition, because the temperature in winter is relatively low, the temperature of the patch itself is relatively low, and the forehead of the sticker is heated slowly. Please increase the contact time between the patch and the forehead appropriately.
