Small Rotational Viscometer

The small rotational viscometer drives a rotor to rotate within the sample via an electric motor, measuring the torque generated by fluid resistance, which is then converted into viscosity data. It is used for monitoring the viscosity of liquid materials such as coatings and inks, ensuring that the flow properties of the materials meet process requirements during production.
Selection
When selecting, it is necessary to match the viscosity range of the material being tested, consider the rotor type and speed configuration, and pay attention to the temperature control function. The operation interface should be simple and convenient for daily rapid testing. The instrument structure must adapt to laboratory space conditions, with clear maintenance procedures.
