Automatic Rotational Viscometer

The automatic rotational viscometer drives a rotor to spin within a sample via a motor and calculates viscosity by measuring the fluid's resistance to the rotor. It is used for on-site quality control and production process monitoring in industries such as coatings and inks, enabling rapid detection of the flow characteristics of both Newtonian and non-Newtonian fluids.
