The utility model relates to the technical field of vacuum pump calibration, and discloses a vacuum calibration instrument which is characterized by comprising a vacuum container, a first pipeline and a second pipeline are arranged on the vacuum container in a communicated mode, the first pipeline is used for being connected with vacuumizing equipment, and the air pressure in the vacuum container can be equal to the atmospheric pressure through an air pressure adjusting part. The detection part detects the vacuum degree in the vacuum container, judges whether the vacuumizing capacity of the vacuum pump reaches the standard or not by setting the duration of vacuumizing and setting the vacuum degree needing to be reached, and ensures the required vacuumizing capacity of the vacuum pump by adjusting the use parameters of the vacuum pump through the data recorded by the host, so that the qualified rate of products is ensured. 本实用新型涉及真空泵校准技术领域，公开了一种真空校准仪器，其技术方案要点是包括真空容器，真空容器上连通设置有第一管路和第二管路，第一管路用于连接抽真空设备，通过气压调整部可以使
