68 degrees??

[ifirefight]

Ok, I got a refractometer and it says ,in order to calibrate it correctly...It needs to be calibrated at a 68 degree room temp..and the calibration fluid need to be also. I live in South Florida...(its been months since Ive felt 68)The next few days MIGHT get cool enough to do this....HOW do the rest of you calibrate your refractometers??? And why is 68 the magic number...what if I calibrated it a 70,will that mess everything up??.

The degree of accuracy would be slightly affected if you tested at 75F instead of 68F. It might be off by .1ppt or so but it won't be significant.
Oh, and it's the refratometer itself than should be at 68F. Not the water and not the air (think refrigerator).
