Introduction
The 3D Formation Tester is a high-precision instrument designed to evaluate the formation quality of sheet-like materials, including paper, cardboard, fiberglass, paper towels, and other nonwoven sheets. Unlike traditional camera-based systems, it uses a laser-type focused beam to measure the optical density of each pixel independently, providing accurate, high-resolution data across a large scanning area.
This technology enables detailed measurement of formation index, internal defects, flocculants, density variations, low-density spots, base weight, and internal standard deviation. Optional surface scanning optics allow for additional surface characterization.
Application Scope
Quality control and R&D of paper, cardboard, and nonwoven sheets
Analysis of recycled paper, coated paper, colored paper, and specialty papers
Evaluation of flocculation, sheet uniformity, and internal defects
Industrial production monitoring for pulp, paper, and towel manufacturing
Surface analysis of steel wire versus felt-processed sheets
Product Advantages
