Single-Column Type Rotational ViscoMeter

The single-column rotational viscometer drives a rotor to rotate in the sample through a motor, measuring the torque generated by fluid resistance and converting it into viscosity. It is used for viscosity testing of liquid materials such as paints and inks, monitoring changes in fluid characteristics during the production process.
Selection
When selecting, it is necessary to match the sample viscosity range with the instrument's measurement range and consider temperature control requirements. The rotor specifications should be compatible with the sample volume, and attention should be paid to the material's corrosion resistance. The operation interface should be user-friendly, and the data output format should be compatible with existing recording methods.
