In the modern field of material science and product development, understanding the durability and performance of products under various environmental conditions is of vital importance. The composite salt spray test chamber, as an advanced environmental simulation device, simulates the salt spray conditions found in marine or other corrosive environments to conduct accelerated corrosion tests on materials, coatings, electronic components, etc., in order to evaluate their corrosion resistance.

Working Principle
The working principle of the composite salt spray test chamber is based on spray and constant temperature and humidity control. Inside the test chamber, compressed air is used to atomize a sodium chloride (NaCl) solution of a certain concentration through nozzles into tiny particles, creating a salt spray environment. Meanwhile, the temperature and humidity within the test chamber are maintained within preset ranges by a precise control system to ensure the stability and reproducibility of the test conditions. In addition, some high-end composite salt spray test chambers are equipped with multiple test modes, such as cyclic corrosion testing (CCT) and alternating salt spray testing (ASST), which can simulate more complex natural environments.
