ModularLine PPS Print Surf Roughness Tester

ModularLine PPS Print Surf Roughness Tester

Measures the roughness according to the Print Surf method

  • Features

    • 3 versions available:
       – 1 head, test direction: bottom-up (standard)
       – Reverse test direction (top-down)
       – 2 heads: simultaneous test from top and bottom
    • 3 contact pressures selectable: 490, 980, and 1,960 kPa


    The sturdy and stable device is equipped with industrial PC and touchscreen and is available in three versions: 1 head (top), 1 head (bottom), or 2 heads (top and bottom). The large display indicates single values and statistics.

    Test description

    The operator places a sample below the measuring head. The measuring head lowers onto the sample after pushing the start button. The bottom platen with backing substrate is lifted and pressed against the measuring head with the preset pressure. Controlled measuring air is admitted to the measuring head and passes from one annular groove, between the sample and the measuring land to the other annular groove. The test takes approx. 3-10 seconds. The measured value (roughness depth) is displayed in μm after the performed test. Furthermore, the compressibility can be measured.


    • Selectable contact pressures:
       – 490 kPa (only for compressibility tests)
       – 980 kPa
       – 1,960 kPa
    • Measuring range: 0.5-8 μm
    • Display of results: roughness (=roughness depth) in μm
    • Measuring accuracy:
       – Pressure differential: ± 0.005 kPa linear
       – Flow: ± 0.5 % of the final value
       – Accuracy of test duration: ± 0.5 s
    • Repeatability: ± 0.2 μm
    • Reproducibility: ± 0.4 μm
    • Measuring direction (depending on version):
       – Bottom-up
       – Top-down
       – Top and bottom
    • Touchscreen for easy handling
    • Parallel printer interface
    • Serial data interface (RS 232)
    • Compatible to PaperLIMS and MiniStat
    • Compatible to PTA-Line
