Cobb Tester
Accurately measure the liquid absorptiveness and moisture resistance of papers, boards, and sheet materials with our precision-engineered Cobb Tester. Essential for quality control laboratories, this apparatus evaluates how effectively treated or untreated substrates resist water, oil, and other fluids. Complete with a heavy 10-kg calibration roller and standard blotting paper, it ensures reliable, repeatable testing performance to verify packaging durability against humidity changes and atmospheric moisture.
Product Overview
Our Cobb Sizing Tester is an industry-standard testing instrument designed to calculate the exact mass of liquid absorbed by a specific surface area over a defined duration. Whether performing a standard 60 or 120-second test for paper sheets or an extended 30-minute test for thick paperboards under a controlled water column, this equipment provides critical data. A lower Cobb value indicates superior liquid resistance, helping manufacturers ensure their packaging materials maintain structural integrity during transit and storage.
