The Cobb Sizing Tester is a laboratory instrument used to determine the water absorbency (Cobb value) of paper, paperboard, and corrugated materials. It measures the amount of water absorbed by a sample over a specified time under standardized conditions, helping evaluate surface sizing and resistance to liquid penetration. Widely used in paper mills, packaging industries, and quality control laboratories, the tester ensures product performance and compliance with industry standards. Its simple operation, durable construction, and repeatable results make it essential for routine absorbency testing.
