    Refractometric Concentration Meter

    Overview Knowledge Standards Terms
    Refractometers utilize the principle that the refractive index of light passing through a liquid is proportional to its concentration, allowing for the direct conversion of the refractive index into solution concentration. They are commonly used for rapid on-site testing of sugar content, salinity, or chemical solution concentrations in beverage production and chemical processes.
    Selection
    When selecting, ensure that the measurement range and accuracy meet the concentration fluctuations of the sample. Handheld models are suitable for fieldwork, while online models are compatible with pipeline installations. Pay attention to temperature compensation functions to address environmental changes, and check whether the anti-corrosion materials match the chemical properties of the measured liquid.
