Digital Rotational ViscoMeter

The digital rotational viscometer drives a rotor to rotate in the sample via a motor, measures the torque value generated by fluid resistance, and directly displays the viscosity reading. It is used for detecting the viscosity of fluids such as coatings and inks, guiding production process control.
Selection
When selecting, consider matching the measurement range and accuracy with the sample characteristics. The rotor model must cover the viscosity range of the fluid to be tested. Pay attention to the compatibility of temperature control functions with the sample. Ensure the operation interface aligns with user habits, and the calibration service is convenient and reliable.
