High-temperature Rotational Viscometer

A high-temperature rotational viscometer drives a rotor to rotate in a sample via a motor, measuring the torque generated by fluid resistance and converting it into viscosity. It is used to detect the viscosity of materials such as coatings and inks under heating conditions, simulating their flow characteristics in production or usage environments.
Selection
When selecting, match the sample viscosity range with the instrument's measurement range, and ensure the maximum temperature tolerance covers experimental requirements. Consider the compatibility of sample characteristics with rotor types, and pay attention to temperature control accuracy and data acquisition methods. Choose the protection level based on the operating environment, while also considering calibration convenience and maintenance costs.
