Principle
The rotational viscometer measures the viscosity by the resistance of the rotor as it swirls/spins in the fluid. The device drives the rotor to set the Rotation speed (e.g. 6/12/30/60 rpm) swirl/spin, and the resistance of the fluid to the rotor is converted into the viscosity value, which is displayed through the digital display interface. The system utilizes High Accuracy Sensors and algorithms to ensure the accuracy and reproducibility of measurement results.
Applications
Laboratory fluid viscosity measurement, low viscosity sample testing, high viscosity sample testing, scientific research experiments, industrial quality control
