Rotational Dynamic ViscoMeter

The rotational viscometer determines viscosity by measuring the resistance of the fluid to a rotor as it rotates within the sample. It is used for detecting the viscosity of fluids such as coatings and inks, guiding adjustments in production processes.
Selection
When selecting, consider matching the sample viscosity range with the instrument's measurement range, ensure the rotor material is resistant to sample corrosion, verify that the temperature control accuracy meets testing requirements, and ensure the operation interface is simple and easy to read.
