Puechased one of these refractometers after learning about how innacurate swing arm hydrometers can be. Easy to use and the included calibration fluid lets you know you are getting accurate readings. I would recommend recalibrating the unit frequently to ensure accurate results.

I' d been testing salinity with a hydrometer for 3 years only to fine out what I thought was 1.025 was really1.028 after testing with the refactometer.

No problems whatsoever with this refractometer. It is very accurate and doesn't slip much. I periodically check it with the calibration fluid and it is rarely off at all.
So much more accurate than a swingarm! By Daniel on 12/18/10

My swingarm showd consistant values of 34ppt which is where I want. However, the refractometer showed that it was actually 37ppt which is way over what my reef tank wanted. Why do we invest so much money in these tanks and cheap out on the most important devices needed? I know I never will again. Thanks BRS for providing an affordable and accurate refractometer. Even better it included calibration fluid that was $9 extra everywhere else I was looking.

Don't trust your expensive reef tank with a 7 dollar swing arm. Get the easy basics right and don't cut corners when it can cost you a lot more in the long run.
I should have bought this earlier. By Steven on 11/22/10

This has been a great product. I used to use a swing arm hydrometer and it was showing 1.024 s/g with the refractometer I was showing 1.030, my swing arm was that off. I have now have my s/g at 1.024 thanks to the refractometer and all my corals are doing AWESOME! I would recommend this to everyone and at $40 how can you go wrong.

It does what it says it does and is well built! Also this has the 35ppt calibration fluid which is what us reefers should be calibrating with.
Good price By Bryan on 9/13/10

Definitely a good price. I was looking at other online sites and found this to be the lowest. Easy to use and will not go back to a hydrometer. Buy it.

After years of using a floating hydrometer I finally got off my butt and purchased a refractometer. Why did I ever wait so long? This is so much easier to use, and I feel it is a lot more accurate also. With the free calibration fluid you simply put a couple drops of the viewing plate, hold it to the light and look through the eyepiece. If it doesn't read 1.026, use the supplied screwdrive to adjust until it does read 1.026. That's it.
