This invention relates to the field of viscosity detection technology, and discloses a rotational viscometer and a method for detecting surfactant viscosity. The invention utilizes a multi-axis leveling mechanism to ensure the horizontal state of the detection mounting frame and the rotational drive mechanism during position adjustment. The rotational drive mechanism outputs a rotational speed through a drive connector, which rotates within the protective frame to detect the viscosity of the surfactant in the measurement container. The leveling of the rotational drive mechanism effectively prevents rotor offset during rotation, thus ensuring the accuracy of the viscosity of the solution obtained from the rotor's output rotational speed. Furthermore, the protective frame ensures that the rotor's rotation occurs within the frame, limiting the detection space and enabling more efficient acquisition of the solution's viscosity.
