Surfaces and interfaces are receptive valuable significant property of chemical molecules due to their potential to develop several phenomena in a self-controlled mechanism. Science of surfaces is vast and is being used industrially since time immemorial. Their accurate and simultaneous estimation is necessary; therefore, the survismeter was used for measuring them along with viscosity. Individually tensiometers, X-ray reflective microscope, and viscometers are used for surface tension, interfacial tension, and viscosity, respectively. These devices are sophisticated, expensive, and individually consume much time and resources with poor reproducibility in measurements. Survismeter is an alternative device for similar measurements together with higher accuracies and reproducibility. It works on a principle of capillary flow and pressure gradient (PG) inside liquid-holding and air-filled bulbs. Several liquids have been used for study with +/- 0.01 mN/m, +/- 0.01 mN/m and +/- 1 X 10(-5) N s/m(2) accuracies in respective data. Copyright (c) 2008 John Wiley & Sons, Ltd.
