If you read the label on Distilled water, you'll see that it goes through an RO process as well as distillation. In addition, nearly all available refractometers intended for aquarium use are actually brine refractometers and not seawater refractometers. The refractive index between brine and seawater are different.

It is good lab practice to always use a standard when calibrating any type of equipment. The standard for a refractometer is pure water and RO/DI qualifies. However, just to let you know, I just ran tap water on two refractometers here in the laboratory and both read 1.000. Even though the tap water is over 300 ppm TDS. So it really wouldn't .

Further I have double checked this with a cheap BRS or amazon unit that I borrowed and confirmed the poor results. When calibrated using RO/DI fluid the unit tests out at 0 ppt. However, when I then go and look at the calibration fluid it reads between 30 and 33 ppt. Yes I dry off the refractometer lens between tests.
