Digital Refractive Index Meter

Digital refractometers determine the concentration of solutions by measuring the refractive index of light in the sample. They utilize a prism and a photoelectric detector to analyze the critical angle of total reflection, directly displaying the refractive index or converting it into concentration values. They are used for detecting the sugar content in beverages, the purity of engine oil, chemical concentrations, and other liquid substances.
Selection
Select the measurement range based on the refractive index range of the sample to be tested. For conventional liquids, choose 0-32 Brix. Consider the sample temperature to determine whether temperature compensation is needed. Choose between portable or benchtop models based on the usage scenario. For chemical environments, corrosion-resistant materials are required. A resolution of 0.1% is generally sufficient for routine testing needs.
