    The calibrated solution is much better more accurate.

    "Virtually all hobby refractometers are NaCl refractometers, not seawater refractometers. When yours reads 35 ppt salinity, you really have 33.3 ppt salinity. If it reads 36 ppt, you really have around 34.3 ppt." and "You can basically use distilled water or RODI to test it but it should already come calibrated from the factory even if it came with solution."
