G.) of sea water by refractive index. What is different about the D D Seawater Refractometer? Almost all hand held salt water refractometers available to the hobby are designed and calibrated for the testing of brine solutions, i. e. sodium chloride, and are not calibrated for the refractive index of natural sea water. Even though the largest percentage of salt in
