[0025] When the device is used for salt spray corrosion test, the test seat 2 is pulled out to slide out so that the object to be tested can be placed on the top of the test table 3. After placement, the first micro water pump 6 on the storage seat 5 in the test seat 2 can cooperate with the first atomizing nozzle 7 to atomize and spray the salt spray liquid in the storage seat 5. At the same time, the top of the test table 3 can be atomized and sprayed by the cooperation of the second micro water pump 10 and the second atomizing nozzle 11, so that the test object on the test table 3 can be sprayed more comprehensively, and then the test object on the test table 3 can be observed through the observation structure on the test box 1. When the inside of the device is conducting the test, the lighting work can be performed through the lighting lamp 14 on the lighting seat 13. While assisting in observation, the arc-shaped lighting lamp 14 can adjust its lighting position and quantity through an external control device so as to show the surface changes of the test object at a suitable angle.
