Viscosity Testing Technique

Viscosity is the amount of internal friction (or internal resistance) between components in a fluid. Products with high viscosity are considered "thick” and flow slowly. Products with low viscosity are considered "thin” and flow quickly and easily. In industrial production and scientific research, the composition or quality of substances is often monitored by measuring viscosity. The measurement of viscosity is closely related to the fields of petroleum, chemical industry, electric power, metallurgy and national defense. It is an important means to control industrial processes, improve product quality, save and develop energy.
