    Handheld Refractive Index Meter

    Overview Knowledge Standards Terms
    Handheld refractometers measure concentration by detecting changes in the refraction angle of light passing through a liquid. By observing the boundary line between light and dark through a prism and eyepiece, the corresponding scale provides direct readings of sugar or salt content. They are used for rapid on-site testing of juices, coatings, cleaning agents, and more.
    Selection
    When selecting, consider whether the measurement range and accuracy meet the sample requirements. Pay attention to automatic temperature compensation and calibration convenience. Check the device's protection rating to ensure it suits the working environment. Confirm the clarity of the operation interface and auxiliary functions such as data storage.
