Vehicle Salt Spray Test Chamber

Vehicle salt spray test chamber is suitable for the salt spray corrosion tests of protection layer of components and parts, electronic hardware components, metal materials and industrial products.

This test chamber typically find application in automotive industry such as salt spray corrosion test of car body, chassis and engine. It can handle neutral salt spray test, acetate spray test and copper accelerated acetate salt spray test.
