Single-Column Rotational ViscoMeter

A single-spindle rotational viscometer drives a rotor to rotate within the sample via a motor and measures the resistance exerted by the fluid on the rotor to determine viscosity. It is used to detect the flow characteristics of fluids such as coatings and inks, and is applied in quality control and process adjustment.
Selection
When selecting, consider the measurement range and accuracy requirements, matching the sample characteristics such as viscosity range and fluid type. Pay attention to the compatibility of rotor specifications with the sample volume, ensure environmental conditions meet operational needs, and verify that the instrument materials are suitable for the sample properties.
