盐干湿试验机主要用于户外盐污染的环境中材料的加速腐蚀试验，本设备是自然状况，以自然环境中较常遇见之状况加以模拟，以数倍于自然环境之苛刻条件加以自合测试，如盐雾、干燥、湿润、常温静置、等环境加以自合，可任意顺序或单独执行测试。与传统试验，如中性盐雾试验（NSS)、乙酸盐雾试验(AASS)、铜加速乙酸盐雾试验（CASS)相比，其在于它能更好地再现发生在户外盐污染环境下的腐蚀。
Climate salt spray chamber is mainly used for accelerated corrosion test of materials in outdoor salt polluted environment. This equipment is the closest to the natural condition. It simulates the situation often encountered in the natural environment and tests itself under harsh conditions several times that of the natural environment, such as salt fog, drying, wetting, standing at room temperature, etc. the test can be executed in any order or separately. Compared with traditional tests, such as neutral salt spray test (NSS), acetate salt spray test (AASS), copper accelerated acetate salt spray test (CASS), its greatest advantage is that it can better reproduce corrosion occurring in outdoor salt pollution environment.
