Ordinary salt spray box is to complete the NSS neutral salt spray test, ASS acetate salt spray test, CASS copper accelerated acetate salt spray test, and the composite salt spray test box generally requires humidity control inside the box, mainly for salt spray damp heat The alternating test also has a dry function.

In summary: the normal salt spray test chamber can only be used for fixed value test, and the composite salt spray test chamber can be used for cycle test.

The compound salt spray test chamber is one of the experimental devices for “anti-humidity, anti-salt fog and anti-mold” in artificial climate environment. It is a kind of environmental adaptability and reliability for the research of machinery, national defense industry, light industry electronics, instrumentation and other industries. Important test equipment.
