HANNA’s Digital Refractometers perform the measurement of sugar (five types), salt (Sodium Chloride), and the refractive index in the food industry. Also, a refractometer is available for the measurement of solvents and anti-freeze (Glycol analysis) in mechanical applications.

Categories are further broken down into refractometers for wine (five refractometers), and seawater. Just some of the industries that may benefit from a refractometer: fruit growers and importers, food and drink manufacturers, wine producers, mechanics and the waste water industry, pharmaceuticals and chemical manufacturing. Salinity testing of natural or artificial seawater, aquatics, and those involved in environmental monitoring.
