    RefractoMeter for Brix Measurement

    Overview Knowledge Standards Terms
    A refractometer measures sugar concentration based on changes in the refraction angle of light as it passes through a liquid. Light is directed from a prism into the sample, and the refractive index correlates with the sugar content, allowing the sugar degree to be read directly from a scale. It is used for process control and quality testing in food processing, such as in juices, beverages, sauces, and other products.
    Selection
    When selecting, consider that the measurement range should match the common brix range of 0-90%, with accuracy meeting the basic requirement of ±0.1%. The sample volume should be suitable for handheld or benchtop designs. The automatic temperature compensation function should adapt to environmental changes, the protection rating should comply with usage scenarios, and the calibration method should be simple and reliable.

    Abbe refractometer measures the refractive index and concentration of resin liquids.
    The Abbe refractometer measures the refractive index of resin liquids using the principle of the critical angle of light, and there is a corresponding relationship between the refractive index and concentration within a certain range.
    Method for Determining the Refractive Index of Resin Using an Abbe Refractometer
    This article introduces the method of measuring the refractive index of resin using an Abbe refractometer. It first explains that the refractive index is an important optical parameter of resin, and the Abbe refractometer, based on the principle of total internal reflection, enables rapid measurement.
