    The sturdy, stable instrument is equipped with a built-in industrial PC and a touchscreen. It is available in three versions: 1-head (top side), 1-head (bottom side), or 2-heads (top and bottom side).

    Test description

    The sample is placed below the measuring head. On pushing the start button, the 10 kg dead-weight lowers onto the sample and helps to hold it tight to the glass plate. The built-in vacuum pump evacuates the selected tank to a vacuum of -50.7 kPa. Depending on the surface roughness of the sample, atmospheric air is drawn in between the glass plate and the sample. The time taken for the vacuum to reach -48.0 kPa (res. 29.3 kPa) is displayed in BEKK seconds. Ten seconds after the test has started a preview is displayed to give an estimation of the result in advance.
