This easy to use ear thermometer features Age Precision? Technology for age-adjustable fever guidance, and color-coded display for an easy interpretation of results. Unlike other ear thermometers, where the cool tip of the thermometer in the ear may result in lower temperatures, this digital thermometer features a pre-warmed tip that ensures accurate temperature readings and is more comfortable. It also features infrared technology that takes a temperature in seconds, and is gentle. The ExactTemp system uses a light and beep to confirm proper positioning, so you can be confident it is being used correctly.
