Oregon Scientific’s Personal UV Monitor with Exposure Timer. Running only $29, this device can tell you based on UV, SPF, and your skin type just how long you should be
tanning on that
. It has a countdown timer and a wrist strap, and it’s waterproof so you can take it to the beach or the pool.
The only flaw with this device—cool as it is—is that it necessitates going outdoors. What I really need is something to calculate the amount of exposure I’m getting from my monitor, so I know when to take a break from blogging.
