fiber-quality-analyzer-360-fqa-360

FQA-360

Code:
SKU:LDA17

The FQA rapidly and accurately measures fiber length, width, curl, % numeric fines, and kink in dilute pulp samples. Optional software is available to measure mean fiber coarseness according to ISO 23713, Fiber Wall Thickness, hardwood/softwood blends, Degree of External Fiber Fibrillation, analyze shives and analyze vessel elements. The patented flow cell resists plugging or fouling and orients fibers for correct image analysis. The FQA meets or exceeds the specification of Tappi Test Method T271, PAPTAC B.4 and ISO 16065-1 and -2. Accessories include the 6 Beaker Carousel and OpTiBlend software.
