Need a quality Refractometer
I bought a Marine Depot brand refractometer a couple of weeks ago. It was cheap and the reviews were great so I bought it. The refractometer optic was scratched and would not hold calibration for more than 24 hours. Heres the thread: http://reefcentral.com/forums/showthread.php?t=1781031
I know there are tons of threads with people asking for refractometer recommendations. I dont want to buy a cheap one for 40-50 dollars. I want to get a quality refractometer that I can use for years to come. The most important thing for me is that it holds its calibration for a long time. I read some people have refractometers that hold calibration for months. Im deciding between these: http://www.drsfostersmith.com/produc...m?pcatid=12132 http://www.aquacave.com/salinity-ref...ments-616.html Which one should I get? Any other recommendations? |

I have a Sybon (Made in China) and it seems to be just fine. I calibrate it every single time I use it; this is a good habit (or so I think.)

How are you calibrating your refractometers, with RO/DI or a solution of a known salinity?

If you can some people to go in with you, you can get a pretty nice Westover Scientific (by Fisher Scientific) lighted ATC refractometer. Price drops pretty drastically if you can order 5+ at a time:

I use a product designed specifically for marine hobbyists:  The dropper top is worth the price of the bottle itself. Bulk Reef sells it.
