Rapid viscometer

The utility model provides a rapid viscometer, which comprises a plurality of cylindrical pipes (1) with the same lengths, wherein the cylindrical pipes (1) are filled with liquids; a test ball (2) is arranged on each cylindrical pipe (1); induction coils (3) are arranged at the same positions of the bottom ends of the cylindrical pipes (1), and are connected with control circuits; and outer frames (9) cover the upper ends and the lower ends of the cylindrical pipes (1). The rapid viscometer is capable of rapidly testing that whether the viscosity of lubricating oil reaches the standard or not, and is relatively small in volume, simple to operate and high in test speed.
