S Summary This article provides a brief explanation of the features of a new viscosity measurement method, the tuning-fork vibration viscometer, accompanied by actual measurement examples. The vibration viscometer measures “viscosity × density,” and using water as an example (the temperature coefficient of the density value is as low as 1/100 of the viscosity value) expresses the “viscosity × density” as the “static viscosity.” As a result, it has become possible to easily perform continuous measurements of various viscosity-related physical property changes. Various measuring methods for viscosity and uncertainties of these methods have already been verified and made publicly available as the JCSS standardized methods for viscosity measurement. Based on these experiences, it is expected that there will be more opportunities for precise viscosity measurements in such areas as research & development, production, and quality control in a variety of industries, thereby further contributing to their development.
