Rapid Viscosity Analyzer

The rapid viscometer measures the torque generated by fluid resistance as a rotating paddle turns in the sample, converting it into viscosity data. It is used to detect the flow characteristics of fluids such as coatings and inks under specific conditions, and to monitor changes in material consistency during the production process.
Selection
When selecting, consider that the measurement range covers the viscosity range of the samples, the temperature control function adapts to process requirements, the rotor specifications match the sample volume, the data interface is compatible with the existing system, and the operating procedures align with the personnel's habits.
