Rotational viscoMeter digital display

The digital rotational viscometer drives a rotor to rotate within a sample via a motor, measuring the torque generated by fluid resistance, and directly displays viscosity data. It is used for detecting the viscosity of fluids such as coatings and inks, guiding production process control.
Selection
When selecting, consider the measurement range and accuracy to match the sample characteristics. The rotor specifications should cover common viscosity ranges. Pay attention to the temperature control function and calibration certificate, and check whether the data output interface meets recording requirements. Ensure the sample volume is compatible with the rotor size, and the operation interface is simple and easy to read.
