Density calculation method for specific gravity cup: p=(m2-me1)/V, m2=total weight of cup and pattern (g), ml=empty cup weight (g), V=cup volume (mm) ratio. Durable: The thickness of the specific gravity cup body is 1.2mm, made of thickened 304 stainless steel material, which is sturdy and durable, not easy to corrode, equipped with a tight lid, a small hole in the middle, no bubbles, and high testing accuracy. Material: The cup body is made of high-quality stainless steel precision machining, which has strong corrosion resistance and oxidation resistance. It not only has a bright appearance, but also has textures inside. Appearance: Cylindrical design, large opening cup design, easy to use, integrated molding, no gaps, good inner and outer wall smoothness, easy to clean. Wide Application: The specific gravity cup is suitable for measuring the specific gravity of various coatings, transparent varnishes, paint viscosity, latex paints, oils, and other liquids.
