Just in time for the first full day of summer, Oregon Scientific releases its Personal UV Monitor, a device that can help you keep your skin from looking like an old worn-out leather shoe when you're old by keeping track of how much ultraviolet light you're exposing yourself to today.
Its countdown timer keeps track of how long you've been in the sun, and when you enter your personal skin type and the SPF (Sun Protection Factor) of your sunscreen, it will calculate your recommended exposure time. Plus, it automatically updates its recommended exposure time when the intensity of the ultraviolet rays changes.
Since you'll probably be near the water when you're catching all those rays, its case is splashproof. And it's probably going to be hot wherever you are, so you'll wonder what the temperature is—it shows you that, too.
