If you really hate refractometers go old school and use a Tropic Marin glass Hydrometer, never needs calibrating. The only rule is just don't drop it.

LOL. I had to unscrew the piece that you look into so far that after I put the rubber piece back on it wouldn't fit in the case.

I've always heard those are insanely inconsistent.....is that true?

Mine was insanely incorrect I ended up selling it and getting the digital refractometer.

Even those are a pain to read.

I use a hydro for brewing beer and I have a hard time reading it.

The optics don't lie.... Just make sure you use a good calibration fluid!

Great thread.

FWIW, the place where I work recently received 2 x Red Sea refractometers. After calibrating with 35 ppt solution (http://www.drsfostersmith.com/produ...b&gclid=CP-Lre7btMcCFUgWHwod938NfQ&kpid=72999), one was off by 5 ppt, the other by 1 ppt.
