HotSpot Sensor Technology: 16 infrared sensors take more than 4,000 measurements to find the hottest point and deliver the most accurate result in just 2 seconds.Hygienic: There's no need to touch the skin. Thermos avoids any contact with saliva, earwax, or other body fluids-making it the most sanitary way to take a temperature.Smart Fever Management: Syncs automatically with your smartphone & app gives an interpretation based on age, fever history & symptoms. Plus the ability to take notes, add photos, and set reminders.Multi-user friendly: Touchscreen lets you assign readings to up to eight users. Since normal body temperature can vary by age, Thermos's LED indicator tells you if a reading is normal or elevated.Medically approved: Thermos is FDA-cleared. The app also includes Thermia, a fever education tool developed by Boston Children's Hospital.
