The DeltaTRAK Salinity Refractometer™ is an optical meter designed to test the salinity of water or brine. Brined products including poultry, bacon, ribs or seafood are often flavored, tenderized and preserved using brine. The Salinity Refractometer displays a direct reading of the specific gravity and concentration (Parts Per Thousand) of salt in water. It can be used to check and maintain stock solutions and dilutions. In the food industry, it is especially effective in the preparation of frozen vegetables, fruits, seafood and ocean byproducts.
