Product Description
Product Overview
The Micro-computer Controller Cobb Absorption Tester is a precision instrument designed to measure the surface water absorbability of paper and paperboard materials using standardized COBB test methods. This essential testing equipment provides accurate results for quality control in printing and packaging industries.
COBB Testing Principle
The COBB value represents the unit area of paper or paperboard that absorbs water under specific pressure, temperature, and time conditions. The calculation formula is: C = (G2 - G1) × 100, where:
- C - COBB water absorbing value
- G2 - Sample weight after testing
- G1 - Sample weight before testing
