[0002] The salt spray corrosion test chamber can assess the salt spray corrosion resistance of materials and their protective layers, as well as compare the process quality of similar protective layers. It can also assess the ability of certain products to resist salt spray corrosion. This product is suitable for salt spray corrosion testing of parts, electronic components, protective layers of metal materials and industrial products. The salt spray corrosion test chamber requires the use of sealing components to seal the test chamber.

[0003] For example, the “Salt Spray Corrosion Test Box” with publication number CN207198014U comprises a box body, a box cover arranged on the box body and a control panel arranged on one side of the box body.
