Fitting on any workspace, the benchtop refractometers determine refractive index, degrees Brix, HFCS, or user-defined liquid concentrations quickly and accurately. Select models have specific designs for measuring different samples at varying concentrations in a target substance. Refractometers are user-friendly and easy to control, providing continuous and real-time readings for all types of liquids. With a sophisticated microprocessor, digital models automatically calibrate to guarantee readings are always precise.
