【High Precision Density Measurement】 Designed for measuring density or specific gravity of paints, coatings, varnishes, oils, and other liquids. Suitable for quality control, formulation checks, and routine testing. 【Durable Stainless Steel Construction】 Made of premium 304 stainless steel with 1.15-1.45mm thickened wall. Strong corrosion and oxidation resistance. Smooth inner and outer walls for easy cleaning—no wire brushes or metal scrapers needed. 【Secure Lid & Easy Calculation】 Airtight lid with central vent hole allows excess liquid to flow out, minimizing bubbles and enhancing accuracy. Density formula: P = (m2 - m1) / V (empty cup weight, filled cup weight, and cup volume). 【Easy to Fill and Clean】 Cylindrical design with wide opening for convenient filling, emptying, and cleaning. One-piece molding with no gaps prevents residue buildup. Ensures efficient testing and easy maintenance. 【Storage Case Included】 Supplied with a protective storage case for safe transport and storage. Keeps testing tool organized and reduces risk of damage. Ideal for laboratories, coating workshops, production checks, and material inspection.
