Disc Rotation ViscoMeter

The rotary viscometer drives a rotor to rotate in a sample via a motor, measuring the torque generated by fluid resistance and converting it into viscosity. It is used to detect the flow characteristics of fluids such as coatings and inks, and is employed in industries such as printing and plastics for production process control and product quality inspection.
