The invention provides a cryogenic container comprehensive performance detecting device which comprises a control system and a vacuum pump set. The control system is in signal connection with two vacuum gauges, a mass spectrometer and a flow meter respectively, one vacuum gauge is connected with the mass spectrometer, and the flow meter is connected with a flow measuring interface. The vacuum pump set is connected with one end of a third vacuum valve and one end of a vacuum fine-adjustment valve, and the other end of the vacuum fine-adjustment valve is connected with the second vacuum gauge. The other end of the third vacuum valve is connected with one end of a first vacuum valve and one end of a second vacuum valve respectively, the other end of the first vacuum valve is connected with a standard leakage hole, and the other end of the second vacuum valve is connected with a vacuum measuring interface. The cryogenic container comprehensive performance detecting device integrates state-specified cryogenic container type experiment, periodic inspection and comprehensive performance testing, the utilization rate of the device is improved, automatic testing is achieved, artificial interference on operating process is decreased, and automatic data storage and intelligent processing are achieved.
