I checked both with water and they both seem to be calibrated. My refractometer says ~12.5 - 13 and the hydro says 1.042 in 80° wort. Even with the temp adjustment its only 1.044. Thats a 5 to 7 point difference. Which should i trust?

I have the same problem. I have two hydrometers and they both read the same, my refractometer was way off and was calibrated with RO water. It constantly reads about 1.012 higher then my hydrometers. I bought a new refractometer and it reads about 1.008 higher and it was calibrated with RO water also.
