L&W TSO Tester

Are you looking for support or purchase information?

L&W TSO Tester is an ultrasonic instrument for measuring Tensile Stiffness Index (TSI) and the Tensile Stiffness Orientation (TSO) properties on sheets and cross machine paper samples. In the QC shift laboratory the results are used to predict the performance of paper, in a sheeting process, in a multicolour printing process, in laser copying machines, and when manufacturing corrugated board. It is also an ideal tool for process optimization, as it allows you to take early action in the head box, press and dryer, saving raw material, as well as time.

Features/Benefits
  • Tool for paper machine tuning and for predicting end use performance at printers and box makers:
    – Automatic measurement of cross directional and machine directional TSI- and TSO-profiles
  • Ease of use:
    – Large touch screen for good overview
  • Quick and non destructive testing:
    – Using ultrasonic technique makes it possible to do quick and non-destructive TSI measurement in all directions of the paper’s plane
    – Rapid measurement – six seconds per test point
