The specific gravity cup features a tight cover with a small hole in the middle to prevent air bubbles and deliver test accuracy. Calculation method for cup density: P(m2m1a)/v1; m1 is the weight of the empty specific gravity cup (g), m2 is the total weight of the filled sample and specific gravity cup (g), v1 is the volume of the cup (g) The specific gravity cup is suitable for measuring the specific gravity of various coatings, auxiliary materials, oil and other liquids The cup body is made of stainless steel with precision machining, and the inner and outer walls have a good finish Applications: quality control in paint and coating production to verify specific gravity of coatings, solvents and additives Applications: density measurement of lubricants and oils during formulation or quality checks Applications: research and development laboratories assessing liquids and additives by determining their specific gravity
