This innovative principle offers a completely new opportunity to characterise and understand the phenomena of dynamic water absorption. Here the water uptake is continuously monitored across a full 100 cm² area of sized paper or board as a function of time. Apart from the total amount of absorbed water over 60 seconds, this technology reveals the different dynamic components of water absorption. Once the operator has inserted the test specimen, the test is done automatically by the instrument as no weighing or blotting of the specimen is required. This way the regular operator time of three minutes for a 60 second Cobb test is reduced to only a few seconds for loading of the specimen.
FEATURESThe specimen is clamped in a closed chamber against a porous membrane saturated with water. The absorbed amount of water is then continuously monitored using a precision level sensor. After a
preset time (e.g. 60 seconds), the test is automatically terminated, free water on the test surface is removed and the clamp is opened up releasing the specimen. A Cobb value is finally displayed together with the curve showing dynamic water absorption as a function of time (see reverse for chart).
