The composite salt spray test chamber is a testing device used to simulate marine environments or other corrosive conditions. It is mainly employed to evaluate the corrosion resistance of materials or products under these harsh conditions. Here is a detailed explanation of its basic working principle and function: Working principle
1. Salt fog generation: The composite salt fog test chamber generates fine salt fog particles by mixing salt solution (typically a 5% concentration of sodium chloride solution) with compressed air. These salt fog particles are evenly sprayed onto the surface of the products or materials to be tested through nozzles.
2. Environmental control: The interior of the test chamber can precisely control temperature, humidity, and salt fog deposition rate to simulate different corrosive environments. For example, it can simulate the high humidity and salt content in the marine environment, or by adding other chemicals to simulate specific types of corrosion.
3. Cycle corrosion: To more realistically reflect the actual usage environment, the composite salt fog test chamber can also conduct cycle corrosion tests, that is, alternating between salt fog corrosion and drying, humid heat, etc. This helps evaluate the corrosion resistance of products in complex environments.If you need more models about our test equipment, please reference our chamber-testing（point）com 
4. Monitoring and adjustment: Throughout the test process, the test chamber continuously monitors and adjusts environmental parameters to ensure the accuracy and reliability of the test results. For example, through standard funnels and measuring cylinders, steam is recovered, the salt fog deposition rate is analyzed, and it is adjusted through nozzles and spray towers. Function
1. Materials Science: In the field of materials science, the composite salt spray testing chamber is used to test the corrosion resistance of materials, simulating harsh environments such as the ocean, in order to evaluate the performance of the materials in actual usage.

2. Automotive Industry: In the automotive manufacturing industry, salt spray test chambers are used to test the performance of automotive components such as the braking system and electrical components in a salt spray environment, ensuring the reliability and safety of the vehicle in various conditions.
