Optimal preparation, operating, displaying and evaluation of measuring

The user-friendly software based on MS WINDOWS (from Version 95), which includes many applications, facilitates adaptation for special test sample requirements and offers excellent tools for evaluating results.

The scope of delivery

• Various measuring methods are available
  • with increasing gas flow (bubble formation frequency) e.g. for strongly foaming samples
  • with decreasing gas flow (bubble formation frequency)
• Incremental and continuous flow change, stop-flow mode for very long surface ages, monitor mode at constant flow rate
• Easy calibration and test routines
• Stored parameters for four different capillaries
• Graphic and tabular online display of pressure, flow rate, bubble formation period and surface tension

Other options

• Calculation of effective surface age based on constant interface (corresponding to a constant interface)
• Viscosity correction at high bubble formation rates
• Special graphic presentation to estimate diffusion coefficients
• Extrapolation to "static" surface tensions and infinitely small surface ages
• Production of user-defined tables in ASCII format
• Polynomial curve fitting for quantifying test curves
