The invention relates to an automatic timing viscosity meter and belongs to the technical field of mechanical devices. The automatic timing viscosity meter comprises a support leg screw, a hand wheel,a platform base, a timing display mounting groove, a timing display, a pressure sensor mounting groove, a pressure sensor, a containing cup positioning slot, a containing cup, a containing cup handle, an auxiliary discharging port, a bolt, a check plate, a main discharging port, a check plate handle, a cross arm large round hole, a liquid to be measured storage cup, a cross arm, a cross arm smallround hole, a locking bolt, a support stand rod, a level gauge, a rubber cushion, a support stand rod mounting hole and a support stand rod screw. By automatically and accurately recording the time interval between that liquid to be measured starts to flow out of the main discharging port and the auxiliary discharging port at the lower end of the liquid to be measured storage cup and that the liquid to be measured completely flows out, the automatic timing viscosity meter can avoid the problem of inaccurate liquid viscosity measurement due to manual timing errors.
