The Milwaukee MR series refractometers are precision optical Instruments used for measuring concentrations of sub-stances in aqueous solutions. They work using the principle of light refraction through liquids. When passing light through a liquid the refracted angle will be shown on the scale determining the amount of dissolved solids in the liquid.

Very simple to use: simply place one drop of your sample on the prism and read the results on the scales immediately! They have adjustable focus and they provide direct readings and can measure concentrations of all kinds of solutions such as: fruit juices, beverages, wine, jam, honey, milk, saltwater, brine, canned foods, cleaning fluids, battery fluids, antifreeze etc.

Models with automatic temperature compensation (ATC) are suitable for applications where the temperature of the samples varies.
