Compliance Standard : ASTM D1544 – Standard Test Method for Color of Transparent Liquids (Gardner Color Scale), Also aligns with ISO 4630 (where applicable)
Application : The Gardner Color Scale is used for the visual determination of color of transparent liquids such as petroleum products, lubricating oils, resins, varnishes, fatty acids, chemicals, and solvents. It is widely used in oil refineries, chemical plants, resin manufacturers, paint & coating industries, and quality control laboratories to assess product quality, consistency, and degree of refinement.
Product Description : The Gardner Color Scale consists of precision color glass standards arranged in a calibrated sequence from light yellow to dark brown. The sample color is visually compared against the standards under controlled lighting conditions to determine the closest Gardner color number. The apparatus is simple, reliable, and does not require electrical power, making it ideal for routine laboratory and production-line inspections.
