This is the infrared thermometer compact enough to be tucked into a pocket or purse that takes accurate forehead temperature readings in as little as one second. About the size of a mini flashlight, the thermometer’s infrared sensor requires just a gentle touch to the forehead to quickly register the temperature. It displays temperature (Fahrenheit or Celsius) in large, bright numerals on its LED display, stores 24 readings in memory, and alerts you when a fever is detected. Automatically shuts off after 30 seconds to conserve battery life. Includes two AAA batteries. 4 3/4” L x 1 3/8” W x 7 /8” D. (5 oz.)
