Oregon Scientific is currently offering the UV Sensor device that tells you the exact moment when you need to get out of the sun. After all, skin cancer and sunburns are definitely no fun despite the pleasures of basking under the solar system's main star. Splashing a liberal amount of sunscreen all over your body won't just do, as there are still limits to its effectiveness. This is where the UV Sensor comes in handy - not only does it tell you the amount of UV rays you are absorbing, it also tells you the exact amount of time you can spend under the sun after keying in various information such as the level of SPF in your suntan solution, skin type, and intensity of UV rays.
Additional features include a countdown timer, a digital clock, and a wrist strap. With summer days just around the corner, it makes perfect sense to pick up this $19.95 device.
