Wool Fiber Fineness Analysis Tester
1. Product Introduction & Applications
The Wool Fiber Fineness Analysis Tester is a precision instrument designed to determine the average wool fiber diameter using the airflow resistance method. When a constant airflow is applied to a wool sample of fixed mass and volume, fibers with different fineness create different resistance levels. By measuring this airflow resistance, the instrument calculates the fiber fineness with high accuracy.
This tester adopts a high-precision, wide-range electronic flow sensor, enabling measurement of wool fibers from 12–50 μm, including ultra-fine wool, making it one of the broadest-range airflow fineness instruments available worldwide.
The system supports one-button operation, fast testing, automatic data processing, USB data export, and software-based report generation in both standard print format and Excel.
Applications:
Measurement of wool top, sliver, scoured wool, and greasy wool
Quality control in wool processing, spinning, and textile factories
Laboratory testing and research institutions
Grading, classification, and raw wool evaluation
Rapid sampling in production lines or purchasing inspections
Key Advantages:
Extremely wide measuring range (12–50 μm), suitable for ultra-fine to coarse wool
Fast test cycle—approx. 15 seconds
One-button operation for simple and efficient testing
High stability using electronic airflow sensors
USB communication with included software for statistics, reports, and data storage
High accuracy (±0.1 μm) in standard laboratory environments
Can maintain 0.2 μm accuracy even in non-standard environments after calibration
24-month warranty for long-term reliability
