whats best way to calibrate refractometers.......discuss!

[Andy]

i am interested on hearing opinions on this matter and the general consensus on which method is best whether it be pinpoint salinity calibration fluid or any other methods people feel get the most accuracy aswell as tips and how to calibrate as effectively as possible.

With an optical refractometer, your best bet is to use a calibration fluid. The closer the calibration is to the measured sample the more accurate it is. If it's calibrated to 1.026 that would be the most accurate when measuring, the further you get away from 1.026 the more it could vary. Don't reas to much into that, I wouldn't scour the world trying to find an exact match but you get the idea.
