The Optical Salinity Refractometer is a precision tool for measuring salt concentration and density in seawater, aquariums, brine solutions, and low-sugar liquids.

With an ATC feature, it delivers reliable readings without being affected by temperature changes.

Ideal for aquarium hobbyists, mariculture breeding, laboratories, and food & beverage industries, this refractometer helps ensure marine life health, optimize fluid concentrations, and improve quality control.

Simply place a few drops of the sample on the prism, close the cover, and read the results instantly.
