Refractometer Calibration

[craig110768]

I just got my refrac. yesterday. I calibrated it with RO water, but didn't need to adjust anything at all, as it was already reading 0.
It mentioned in the very few brief instructions that if i need to "recalibrate" it, it needed to be at 68degrees. How would I bring that to 68 - put it in a fridge? I live in Florida!!
I'm just wanting to make sure its accurate, or maybe I need to recalibrate it.
I got it from Northcoast Marine (80 bucks). Has anyone else had this issue.
Any suggestions.

I'm glad you brought this up, as I too am interested in getting the best refract and would like opinions on which is best.
I'm going to move this over to the Equiptment Forum, though, as its a better spot for it.
Thanks for posting the topic!
