    Refractive Index Measurement Device

    Overview Knowledge Standards Terms
    The refractometer measures the refractive index by detecting the deflection angle of light as it passes through a sample. It is used for composition analysis and quality control of materials such as coatings and plastics, as well as for determining substance concentration and purity in ink formulation and paper coating inspection.
    Selection
    When selecting, consider whether the measurement range covers the refractive index of the sample and whether the accuracy meets detection requirements. Pay attention to temperature compensation functionality and the simplicity of the operation interface. Choose a contact or non-contact probe based on the sample's form, and verify the instrument's calibration convenience and environmental adaptability.

    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.
