Rotational Viscosity and Consistency Meter

A rotational viscometer measures the fluid viscosity by detecting the resistance encountered when a rotor rotates in the sample. It is used for quality control and production process monitoring in industries such as coatings and inks to ensure that the flow properties of products meet the required specifications.
Selection
When selecting, consider the measurement range matching the viscosity of the sample, rotor shape adapting to the characteristics of non-Newtonian fluids, adjustable rotational speed meeting shear rate requirements, temperature control ensuring measurement consistency, and corrosion-resistant materials handling chemical samples.
