cobb water absorption testing equipment
COBB TESTER The cobb tester is a simple instrument which measures the water absorptiveness of paper, cardboard and corrugated fi breboard under standard conditions. The water absorptiveness is a very important and useful parameter in the specifi cation of paper and board for use in the packaging and printing industries.COBB Tester is used to perform the COBB Test, which is the water absorption property of paper, paper board and corrugated fibreboard. Example: – A new currency note has a very low COBB Value. i.e. Even if you dip it in water, it will absorb very less water. – A newsprint paper on the other hand has a very high COBB Value.
