【High-Precision Density Meter】 Features a tight-fitting lid with center vent to release excess sample, ensuring bubble-free accuracy. Measurement error within 1 mg (0.001%). 【Premium Stainless Steel Build】 Crafted from durable 304 stainless steel with precise workmanship. Smooth interior and exterior finish prevents liquid adhesion and ensures easy cleaning. 【User-Friendly Cylindrical Design】 Large opening allows easy filling and cleaning. Clean and dry promptly after each use to maintain accuracy. Light-protected surfaces for stable, repeatable results. 【Simple Density Calculation】 Calculate density effortlessly: P = (m2 - m1) / V, where m1 = empty cup weight (g), m2 = sample + cup weight (g), V = cup volume (ml). 【Versatile Applications】 Ideal for testing density/specific gravity of paints, varnishes, coatings, auxiliary materials, oils, and industrial liquids at controlled temperatures.
