The invention discloses a full-automatic condensation point measuring device, and belongs to the technical field of oil physical property measurement. The measuring device adopts two measuring modes to measure oil condensation points and comprises a condensation point test tube, a temperature sensor, a camera probe, a stress piece, a motor, a position sensor, an angle sensor, a heating-refrigeration circulator, a PC machine, a PLC controller, a modulation processor and an injection pump, the heating-refrigeration circulator, a liquid tank and a liquid storage pot are connected and form a circular loop, and the stress piece is inlaid in the inner wall of the condensation point test tube; the camera probe monitors and judges solidification degree of a sample, is placed to the condensation point tube, and rotates to the 45-degree oil sample scale line position, when the motor drives the condensation point test tube to rotate, the camera probe and the stress piece synchronously measure oil, the efficiency is high, the reliability is high, human resources are greatly reduced in a technical aspect, and the measuring device belongs to a high-performance intelligent automatic device.
