Product information "D-D sea water refractometer" Most of the refractometers currently available in the hobby area are for measuring salt water (sodium chloride or saline solution) and not for real "sea water". Even though seawater consists mostly of sodium chloride, it also contains other components such as Magnesium and calcium, which change the refractor index slightly and thus deliver different and inaccurate results.
