C0005 - C0006 - Cobb Moisture Absorption Test Ring and Roller

Product details

This method for measuring water absorption of sized papers is used all over the world. 

A dry test piece of suitable paper is placed under the cylinder. The 100ml of water is 

poured over the test piece. After a specified time the water is poured off and the test 

piece is placed on standardised blotting paper. Another blotting paper is placed on top of 

the test piece and the excess water is removed by means of the roller.
The test piece is then weighed again and the results are calculated and reported as 

absorptiveness in grams per m2, according to the standard method.
