Digital rotational viscometerMeasure viscosity through rotational motion. When the rotor (usually cylindrical or disc-shaped) inside the instrument rotates at a constant speed in the fluid, the fluid will generate viscous resistance to the rotor, and the torque generated by this resistance can be measured by sensors. According to torque（T）Viscosity (η), rotational angular velocity of the rotor (ω), and correlation coefficient of geometric parameters of the rotor（K）The relationship between themT=Kηω， Given the known angular velocity and geometric parameters, the viscosity of the fluid can be calculated.
