I can get this refractometer from JL Aquatics for $50. Has anyone tried it? Is it accurate? Other places I've looked all sell their refractometers for about $80 and I am just wondering if their is a difference. Thanks!

For saltwater purpose it is more than enough. Make sure it is calibrated properly.

Thanks for the input! I think I will go ahead and order it.

I just bought one this week. I used distilled water to calibrate it, leaving it on the lens for about a minute to adjust to the correct temperature. It was out of calibration by a couple points when I received it, so I turned the screw slightly with the supplied screwdriver and it is now accurate. J&L had another refractometer for almost $10 more, but the only thing really different is that it came with its own "pure" water. Supposedly, "they look like they come from the same plant".

Mine was almost dead on when I got it. Excellent instrument, and a decent price.
