Cobb Sizing Tester

Cobb sizing tester is used for fast determination of the quantity of water absorbed by a paper or board in a given time. The Water absorptiveness (Cobb value) of a substance is defined as the mass of water absorbed in a specific time by a 1 sq. meter sample of paper, board or corrugated board, under standardized conditions.

Cobb Tester measures the amount of liquid penetration into a sheet of Paper, Cardboard or Corrugated Board. The Cobb sizing Tester consists of a cylindrical container clamped to a flat base with a flexible backing onto which the sample is placed. Cobb sizing tester provides a simple, standardized method for fast determination of the quantity of water absorbed by a paper or board at a given time.
