    Abstract

    Near InfraRed (NIR) Spectroscopy was used to measure the consistency, freeness, tensile and tear strength and light scattering coefficient from the refined high consistency pulp. The measurements were done using an in-line TQA analyzer, which was installed after the secondary refiner in a Finnish TMP plant. The results proved that the consistency, freeness, and tensile index can be measured using the NIR spectroscopy. Also, possibility to measure the light scattering coefficient exists. In addition to the measurement technology itself special attention shall be paid to process sampling, sample handling and calibration methods.
