The touchfree thermometer by sanomedics provides you with a non-invasive way to take your child's temperature - even while they are sleeping. And it's incredibly easy to use. Simply aim the unit's sensor toward the forehead, two inches from the skin, and press the button and in one second the temperature reading is displayed on the large backlit color led display. The device has a talking feature in 3 languages - english, spanish and french and can also be put in quiet mode so as not to disturb or awaken anyone. It has a memory of the past 32 readings. The device's touchfree technology allows you to check much more than a person's temperature: the unit can be used to check the temperature of a bottle, food, air temperature or even bath water.
