Picked up a refractometer on a bit of a whim at the LHBS today. I'm pretty excited.
I've got some questions, though for those who have used these before. First off, I'm worried about temperature. I'm sure a droplet of water cools very rapidly, but what is the safe temperature range for these things? The one-page manual didn't mention anything.
What the manual did mention was that I should not use water to clean it, and then it went on to warn about scratching the lense. What's the proper way to clean these?
