The COBB absorption tester is mainly used to measure the surface water absorption of sized paper and cardboard, including corrugated fiberboard. But it may be not suitable for paper and cruddy paper with a density lower than 50g/m2. Likewise, it may be not applicable for loose paper (for example, newsprint) or unsized paper (for example, blotting paper) or other paper with high water absorbability. This instrument is only capable of testing surface water absorption of paper and board. It is not applicable to exactly evaluate the writing performance of paper and board.
