Is the timing resolution satisfactory?
Absorbent materials and surfaces which experience hydration call for systems with sufficient time resolution to follow these dynamic phenomena. The FT125/135 quality systems make measurements several times per second, whereas the FT200 and 4000 systems operate at much higher speeds, with at least .016 second resolution. These systems can study absorption phenomena on all kinds of surface. Here’s an example of a time-slice from a study of water drops on an open-weave surface, following absorption at 1/60 second per video frame. In this case, the absorption rate is a function of chemical treatment of fibers in the weave.
