When tempted to think I know all there is about surface tension measurement, further information brings me back to earth. I’m conversant with the principal applications: surfactant analysis, plating, detecting contaminants, development of ink and the like. I have assisted customers to set up and calibrate duNouy Ring tensiometers for most applications -- all the while taking for granted that the Ring technique was the method of choice -- with only infrequent questions arising about Wilhelmy Plate tensiometers.

Automatic digital tensiometers are expensive - three to four times more so than a high-precision manual tensiometer. We hope to clearly depict when an automatic digital tensiometer is not merely nice to have, but essential.
One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.

You may recall that I promised to offer my interpretation as to how Surface Tension is related to Viscosity.
To begin with, liquid surface tension and viscosity share a common trait: they both involve properties of fluids. After that, things start to get murky.
