In order to solve the restriction problems of environment and volume appeared in phase difference test for low frequency vibration velocity type vector hydrophone, the test device for phase difference of vector hydrophone has been designed on the basis of analyzing the test principle using sound pressure, vibration velocity sensors for vector hydrophone. The inter?comparison verification of this device and standing wave tube is conducted, the result indicates that this device can satisfy the test requirements for phase difference of vector hydrophone and it is more accurate than the standing tube in very low frequency range. The test and analysis with different quantity and placement mode of sensors are carried out;it is found that the vibration velocity, sensor quantity and placing depth of the sensor do not affect the test result of the phase difference.
