Cobb Water absorption tester 61-PPT108 Catalog

Cobb Water absorption tester 61-PPT108

Overview :

Cobb Water absorption tester 61-PPT108 measures water absorption of sized paper, paperboard, and corrugated paper using the Cobb method. It features a (10 ± 0.5) kg metal roller and an inner cylinder area with 50 mm height for testing samples up to 125 mm diameter. Designed for absorbency papers in the 200 to 250 g/m² range, it delivers an absorbency speed of 75 mm/10 min under standard conditions. The overturn structure ensures ease of operation, suitable for quality control laboratories in packaging, pulp and paper, and material testing facilities requiring precise moisture resistance evaluation.Lab Expo
