I like the Exergen TemporalScanner because with a gentle stroke of the forehead, I can get a person’s temperatureaccurately and almost instantly — without having to stick something in their ear, mouth, or any other orifice. I can even check a child’s temperature while they sleep. It’s very easy to use — but do read the instructions to get the right swipe motion.
The device takes 1,000 readings per second, selects the most accurate among them, and adjusts for room temperature to give you the temperature of the temporal artery (near the temple) — which is an earlier signal of disease than rectal temperature. This temporal artery thermometer is more accurate than ear thermometers and is less affected by the sources of error that can make oral or underarm temperatures misleading. (However, for many purposes, temperature precision isn’t that important. Just knowing whether there is a fever or not is far more important than knowing the temp within a few tenths of a degree. And often fever is helpful, anyway.) But accurate thermometer readings can bring great peace of mind.
I use one of these at our home and carry one with me everywhere in my pediatrician doctor’s bag. -- Alan Greene, MD
