now having said that refractoemters can be wonkey also.. you have to buy a quality unit with temp compensation. you do get what you payfor in refractometers and personaly I would not buy one under 100 bucks.

Here is the author's concluding opinion after testing 6 USED hydrometers.
"It is my opinion after seeing these results that plastic hydrometers are perfectly acceptable for use in the hobby. I would say they are even acceptable for use in research. Their precision appears to be well within the range of projects I’ve seen conducted in laboratories. Their accuracy is variable, but with a known (and easily found) correction factor these hydrometers perform quite well."
I bet after one year, we looked at the results of 6 refractometer readings, we would have 6 different readings as well for the reasons given in my earlier post.
But I agree that if you spend good money for a quality refractometer, carefully clean it after use, diligently follow the calibration procedures, and if you are the type that washes and dries your dishes immediately after use and put them away, a refractometer is for you.
