2 SITA science line t60
SITA science line t60 is a hand hold tensiometer for measuring the dynamic
surface tension of liquids up to the semi-static range. The device works by
measuring bubble pressure. This is done by pumping air through a capillary
with the radius r into the liquid to be analysed. According to Young-Laplace,
the difference in pressure p which is needed to form a bubble is
proportional to the surface tension :
The device measures the
difference in pressure p and
transforms it into a reading of surface tension. Simultaneously, it records the
bubble frequency, the lifetime of the bubbles and the temperature of the
liquid.
