Overview

The salt dry wet composite corrosion test chamber is a device that can independently perform salt spray neutral test, corrosion resistance test, dry test, moisture test, static test, as well as salt spray, dry wet, and static mixed test; Compared with traditional accelerated corrosion tests such as neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS), its advantage is that it can better reproduce corrosion that occurs in outdoor salt polluted environments; The salt wet dry composite corrosion test chamber can achieve automatic cyclic testing of salt spray, wet heat, and dry without the need to move the product, making it easy to use.
