Water absorpitiveness of sized (non-bibulous) paper, paperboard and corrugated fibreboard (Cobb test)

  • TMI 61-04 Cobb Sizing Testers

    Cobb sizing testers provide a simple, standardized method for fast determination of the quantity of water absorbed by a paper or board in a given time.

  • TMI 61-76 Automatic Cobb Tester

    This innovative principle offers a completely new opportunity to characterize and understand the phenomena of dynamic water absorption.
