Paper Water Absorption Tester
The Paper Water Absorption Tester is a precision laboratory instrument designed to evaluate the water absorption characteristics of unsized paper and paperboard. By measuring the capillary rise of liquid in paper samples over a specified period, it provides accurate and reproducible results for quality control, research, and product development in the paper, packaging, and printing industries. This instrument is essential for determining paper performance in applications sensitive to moisture absorption. (Not suitable for papers or boards with capillary absorption height less than 5 mm within 10 minutes.)
Application
The Paper Water Absorption Tester is used to determine the capillary liquid absorption height of various unsized papers and paperboards. It is widely applied in laboratories, quality control departments, and research institutions for testing paper absorbency.

FAQ
1. What is this product?
The Paper Water Absorption Tester is an instrument for measuring the capillary absorption height of unsized papers and paperboards.
2. What is it used for?
It evaluates how much liquid paper or paperboard absorbs over a fixed time, providing critical information for paper quality control and research.
3. How does it work?
Paper strips are placed in the tester, exposed to a standard liquid, and the capillary rise is measured using precision scales. Multiple strips can be tested simultaneously for accurate comparison.
4. Why is it important?
Capillary absorption affects printing, coating, and packaging performance. Testing ensures paper materials meet quality standards.
5. What types of materials can be tested?
Unsized papers and paperboards with a minimum capillary absorption height of 5 mm within 10 minutes.
