Paper PerFect Formation Analyzer – Optest (PPF)
Characteristics
PPF measures the uniformity of paper at several floc sizes or scales of formation. Properties such as printability and strength properties are strongly correlated with paper uniformity at very particular forming scales.
Samples are easily compared to selected reference sheets such as a competitor’s paper or the “best” sheet produced on a particular paper machine (RFV- Relative Formation Values).
Valmet Fiber Image Analyzer – Valmet FS5
Characteristics
Valmet FS5 is a fiber analyzer designed for laboratory use. Using samples provided by the operator, it analyzes the fiber dimensions (length and width), fines particles (fines), coarseness, fiber curl, and several other properties, including Vessel cells.
Uses
A ultra high definition (UHD) camera captures grayscale images from which the analyzer determines various fiber properties by means of image analysis. Sample fibers are imaged in the measurement cell with 0.5 mm depth of field according to standard ISO 16065-2.
Technical specs
Optics & camera :
Image size:~ 16.2 x 13.5 mm
Smallest measurable particle:< 1 µm
Measuring rate: typically: 50,000–100,000 fibers / minute Measuring cell Depth :3 mm
