    Refractive Index Meter

    Overview Knowledge Standards Terms
    A refractometer calculates the refractive index by measuring the angle at which light bends when passing from air into a sample. It is used to detect liquid concentration, purity, and analyze composition, monitoring solution ratios and quality in the chemical, food, and pharmaceutical industries.
    Selection
    When selecting, consider that the measurement range should cover the refractive index of the sample to be tested, and the accuracy should match the detection requirements. Pay attention to the temperature compensation function. Handheld models are suitable for rapid on-site testing, while benchtop models are suitable for precise laboratory measurements. Check the calibration certificate and sample volume requirements.

    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.
