Rotary Torque ViscoMeter

Rotational torque viscometers measure fluid viscosity by detecting the torque resistance encountered when a rotor rotates within a sample. They are used to analyze rheological properties in industries such as coatings and inks, and to monitor changes in material viscosity during production processes.
Selection
When selecting, it is necessary to match the sample viscosity range with the instrument's measurement range, and consider temperature control requirements. Choose an appropriate rotor based on the sample properties, pay attention to measurement accuracy and repeatability indicators, and ensure the instrument's material corrosion resistance meets the testing requirements.
