Sodium Chloride
Digital refractometers are available to measure sodium chloride in solutions used with food. The optical instruments employ the measurement of the refractive index to determine sodium chloride concentration in aqueous solutions.
The instrument intended for the food industry uses internationally recognized references for unit conversion and temperature compensation. It can display the measurement of NaCl concentration 4 different ways: g/100 g, g/100 mL, Specific Gravity, and °Baumé. It is not intended for seawater salinity measurements.
