Red Sea Seawater Refractometer

Got this Red Sea Seawater Refractometer for sale. It's the Reef-Spec model which is way more accurate than those cheap hydrometers for checking your tank's salinity. It has the integrated automatic temperature compensation so you dont have to worry about the water temp messing up your reading. Comes in the original hard case. Perfect if you're serious about your reef tank or saltwater setup. Case has a few scuffs but the tool itself is solid.
