About This Product
The Cobb test shows how much water a sheet of paper or board absorbs through its surface in a fixed time, which indicates how well it is sized. The cylinder is clamped on top of the paper sample, a measured amount of water is poured in, and after the set time the water is poured off. The paper is then blotted with a roller and weighed again to find the water taken up. The pivoted assembly makes pouring off quick, and the brass roller is used for the blotting step. The Cobb Tester can be supplied and exported to buyers in Croatia, United Kingdom, Zambia, Grenada and Indonesia.
