A refractometer is a simple, robust and accurate way of measuring the salinity within your aquarium and should be used by every serious marine aquarist.
When you need absolutely accurate salinity conditions in your aquarium, you’re going to need an H2 Ocean Seawater Refractometer. Unlike other refractometers on the market, the H2 Show Refractometer measures “true” seawater salinity levels, instead of just saltwater. This means that it measures usually unaccounted for elements such as calcium and magnesium as well as sodium chloride, giving highly accurate, precise results.
