Technical Field

[0001] The invention relates to the technical field of salt spray testing, in particular to a salt spray testing device in which a single machine group controls multiple boxes. Background Art

[0002] Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume of space - a salt spray test chamber. Multiple people are required to control each salt spray test chamber to evaluate the salt spray corrosion resistance quality of the product.

[0003] Existing salt spray test chambers are equipped with anti-corrosion racks to support products. Products can be placed on the racks at an angle or lying flat. For some fire-fighting equipment such as fire extinguishers, their parts may rust and corrode during long-term storage.
