Coating Rotational ViscoMeter

A paint rotor viscometer drives a rotor to rotate in the sample via a motor and measures fluid resistance to obtain viscosity values. It is used in the production and quality inspection processes of liquid materials such as paints and inks to monitor flow characteristics.
Selection
When selecting, consider matching the measurement range to the sample viscosity, ensuring the rotor material is corrosion-resistant, having adjustable speed to accommodate different shear rates, temperature control to meet testing environment requirements, and a user-friendly interface for daily operation.
