Working viscoMeter

The working viscometer drives a rotor to rotate in the sample via a motor, measuring the torque generated by fluid resistance and converting it into viscosity. It is used for on-site rapid testing of the flow characteristics of fluids such as coatings and inks, guiding production formulation and process control.
Selection
Select the corresponding range model based on the viscosity range of the material being measured; match the rotor shape according to the material characteristics; choose portable or fixed type based on usage scenarios; determine the protection level according to environmental conditions; ensure ease of operation to match personnel skills.
