    ISO Fineness Scraper Gauge

    Overview Products Knowledge Standards Terms
    The ISO fineness gauge uses a graduated wedge-shaped groove scraper to draw evenly across the surface of a coating or ink sample. The scale value corresponding to the position where particles become visible is observed. It is used to determine the degree of dispersion and the maximum particle size of solid particles such as pigments and fillers. It is suitable for quality control and production process monitoring in industries such as coatings and inks.
    Selection
    When selecting an ISO fineness gauge, ensure that the measuring range matches the fineness range of the sample. The material should be corrosion-resistant and wear-resistant, with clear and precise scales. Consider compliance with standards such as ISO 1524, ease of operation, and maintenance costs. Determine whether a single-groove or double-groove specification is required based on the types of commonly tested samples, and verify that the accompanying standard plates are complete.
