Brockfield DV ViscoMeter

The Brookfield DV viscometer measures the torque generated by fluid resistance through a rotor rotating in the sample, converting it into viscosity data. It is used for detecting the viscosity of fluids such as coatings and inks, guiding production formulation and quality control.
Selection
When selecting, consider matching the rotor model to the sample viscosity range, pay attention to temperature control requirements, choose stainless steel or special material rotors based on the sample's corrosiveness, and ensure the speed range covers testing requirements for both Newtonian and non-Newtonian fluids.
