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.

I have used the products and must say a very easy to use and robust instrument. It is very easy to calculate the absorbency of the Paper products using the Cobb Sizing Tester from Presto.

It is a very simple to operate but useful instrument for corrugated industry. Testing instruments made by Presto always make testing process very easy.
