Refractive Index Test Instrument

A refractometer calculates the refractive index by measuring the deflection angle of light as it passes from air into a sample. It is used to identify material purity, detect concentrations, and monitor the properties of liquids and transparent solids in the chemical, food, and pharmaceutical industries.
Selection
Select the Abbe type (for liquids) or digital type (for solids) based on the sample state; the measurement range should cover the material to be tested; the temperature control function should accommodate heat-sensitive samples; consider the need for automatic sampling and data export; calibration accessories must be complete.
