Aquarium Hydrometers & Refractometers We have hydrometers, electronic salinity testers, and both digital and non-digital refractometers for measuring aquarium salinity. Hydrometers are cheap, but not that accurate. Refractometers are more accurate and last longer. We have our own MarineAndReef.com REEFractometer.If you need salt, we have that as well, but it is not the best price because it's very expensive to ship. It's one of those things we don't mind you getting at the local store. Useful Links: Hydrometers & Refractometers Article. Related Products: Aquarium Salt. |
