Taking a child's temperature can be difficult, but not with this Exergen Temporal Artery Baby Thermometer. By simply stroking you child's forehead, you'll get an accurate body temperature. This gentle scanner registers heat emitted from the body. This is convenient to use with young children as you can take their temperature while they are sleeping without bothering them. A red light indicator and a gentle beep let you know when an accurate temperature has been reached.
