A digital thermometer to track your temp, this non-contact device works by using infrared technology to scan your forehead without on-skin contact. Quick-one second results can be shown in Fahrenheit or Celsius, and the thermometer holds up to 20 sets of data, making it an excellent choice for workplace use. Two AAA batteries power the unit, so there's no need for charging time, it's always ready to go. Read temperature results on the clear LCD Display, and you'll know for sure if you have a high temp with the Fever Alert. Prevent the spread of illness by catching fever right away.
