We use the DH-300 here in Madison and it works well for us. Sample size we use is 3” x 3” which is about the max size. Would be better if one of the other models can use a larger sample size.

Automatic Cobb Water Absorption Tester / Meter / Testing Machine / Equipment / Instrument for Paperboard

 

Full-Automatic Water Absorption Tester is designed according to the basic parameters and requirements stipulated in GB/T1540-2002 Water Absorption of Paper and Paperboard.This standard is suitable for determining the surface water absorption of various paper or paperboard . But it does not apply to the accurate evaluation of the writing performance for paper or paperboard.

 

 

Features:

 

Surface water absorption (Cobb) value for Paper and paperboard:

 

the unit area of paper and cardboard in a certain pressure and temperature, within the time specified the absorption of water by surface to g / m*m meter.

 

C=(G2-G1)×100. Where: C-value of Cobb water absorption ; G2-the sample quality after absorbing water; G1-the sample quality before absorbing water.

 

Paper and cardboard absorbing tester is the conventional instrument of the paper and cardboard surface water absorption,also called the weight of paper surface absorption tester. The instrument adopts Cobb test method of the various methods in the absorption test, it is also called Cobb absorption tester.
