Rotational Torque ViscoMeter

A torque viscometer reflects viscosity by measuring the resistance torque experienced by rotating components in a fluid. It is used to detect the flow characteristics of fluids such as coatings and inks, guiding formulation adjustments and production process control.
Selection
When selecting, consider matching the viscosity range of the sample to be tested with the instrument's measurement range, pay attention to the compatibility between the rotor specifications and the sample, ensure the temperature control accuracy meets the requirements, and check whether the data acquisition method aligns with operational habits.

Practical Guide to Selecting Rotors and Speeds for Rotational Viscometers
A rotational viscometer measures viscosity by detecting the resistance encountered by a rotor rotating in the sample. When selecting a rotor, it is necessary to consider the estimated viscosity range of the sample, ensuring that the torque reading falls within 10% to 90% of the instrument's measurement range, while also taking into account the sample volume and rheological properties.
