Digital salinity meter range: Digital salinity refractometer for measuring salt solution, salt food and water, brine, such as: diluted soy sauce, ketchup, sauces, seasonings, pickles, seasoning, mayonnaise, etc. The concentration and design. For agriculture, food production and field operations have very useful, with automatic temperature compensation system, especially ideal for field work. Just about 1.0ML poured enough sample measurements. Salinity series application in the field of aquaculture, aquarium, saline preparation and so on. For the rapid determination of salt (sodium chloride) solution concentration or refractive index weight percent.
