Surface Tension Measurements with the program SCA20

  1. Apr 7, 2010 #1
    I start working with the OCA15plus tensiometer and I don't know what the three red lines that appear in the program SCA20 means and how should I position them in the image of the drop on an analysis of surface tension by pendant drop method, for example.

    Can anyone help me?

    Do you have a manual? Or have you tried to locate one?

    Yes, I do. But the manual just explain about two lines and nothing about the third.
    According to the manual, you have to set the upper boundary line near the end of the dosing needle, and the secondary bounding line defines the area from which drop is taken.
    But this information is not explainable enough.

    Perhaps meaning of these lines is explained somewhere earlier?
