Digital Type RefractoMeter

Digital refractometers measure the critical angle at which light passes from the sample into a prism, converting this into a refractive index value. They are used to detect liquid concentration, purity, and component ratios, aiding in quality control across industries such as chemicals and food.
Selection
Select the appropriate range and accuracy based on the type of sample to be tested; consider temperature compensation to adapt to environmental changes; examine the instrument's calibration methods and data output interfaces; compare the ease of operation and maintenance costs across different brands.
