Product Description

ISO535 Cobb Absorption Testing Machine for Paper and Cardboard

Product Description

Cobb water absorption tester is used to test the water absorption performance of paper and paperboard surface, that is, the water resistance of paper and paperboard. Weigh a surface immediately before and after the specified time of exposure to water, and then suck it dry. Results of mass increase in grams per square meter (g/m ²) express. The test area of the standard model is 100 cm ².
Standard: GB/T1540, ISO 535, QB/T1668
