Double Rotating Cylinder ViscoMeter

A double-cylinder rotational viscometer generates shear through the relative rotation of the inner and outer cylinders, measures the resistance of the sample, and converts it into viscosity values. 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 viscosity range of the sample with the instrument's measurement range, paying attention to temperature control accuracy and rotor compatibility. Choose an appropriate rotor based on the sample characteristics to ensure accurate and reliable measurement data.
