can i use the tunze 50ms solution to calibrate a refractometer.

I tried it by it reads really low, does not seem correct
 
This would theoretically be possible, I don't have the conversion table handy but if you remind me when I return to my office on May 24, I will look up the conversion.
 
This could be because the conductivity fluid is a KCL solution and it may be the refractometer needs a mixed salt solution or NaCl to work properly.
