Dynamic Rotation ViscoMeter

A dynamic viscometer measures the resistance of a fluid to motion by rotating or vibrating components within the fluid to determine its viscosity. It is used to monitor the viscosity of fluids such as coatings and inks during production and application, ensuring process stability and product consistency.
Selection
When selecting a dynamic viscometer, consider matching the measurement range to the viscosity of the sample, determining the appropriate fixture type based on the sample volume, ensuring temperature control corresponds to process conditions, avoiding corrosion through material compatibility, meeting monitoring needs with accuracy, and ensuring ease of operation to suit the usage environment.
