How to choose the viscosity measuring instrument correctly?
Viscosity measurements: absolute viscosity and relative viscosity. Absolute viscosity is divided into two kinds of dynamic viscosity and kinematic viscosity, relative viscosity, such as en viscosity, viscosity and Redwood viscosity, and other methods of expression.
In actual use, more commonly used for dynamic viscosity and kinematic viscosity of two. Dynamic viscosity is represented by a rotational viscometer, and kinematic viscosity is represented by capillary methods.
There is indeed a variety of rotary viscometer, the capillary and cup type, ball type
