A new device has been developed which entails sequentially fast measurements of surface tension, the density and the viscosity of liquids. In this new device, the surface tension is quickly calculated by the sum of the different contributions from the pressure difference in bubbles, the number of bubbles in 5 s and the capillary diameter. The measurement of the density and the viscosity are based on the Archimedes principle and the rotating cylinder method. The measurement range of the surface tension, the density and the viscosity is 17-75 mN/m, 0-2.0 x 10(3) kg/m(3) and 10-10(5) mPa s, respectively. At 295 K temperature, some experiments on the glycol and glycerol have been made, and the results show that the accuracy of measuring the surface tension, the density and the viscosity is below +/- 1.0%, +/- 1.0% and +/- 1.5%, respectively, and that the reproducibility is satisfactory.
