Torque-type ViscoMeter

A torque viscometer drives a rotor to rotate in a sample through a rotating shaft, measuring the torque generated by fluid resistance to convert into viscosity. It is used for detecting the viscosity of fluids such as coatings and inks, guiding adjustments in production processes and quality control.
Selection
When selecting, consider matching the viscosity range of the sample to be tested with the instrument's measurement range. Choose an appropriate rotor based on the material's characteristics. For high-temperature samples, a temperature control system is required. For corrosive fluids, use rotors made of corrosion-resistant materials. Additionally, balance operational convenience with data output requirements.
