Salt spray test (neutral, acidic, copper accelerated) can be done, all models can test neutral test, acidic and copper accelerated must use 90PH or above box type, because the required test temperature of these two tests is higher, the plate is too thin and easy to deform, and the above are standard test boxes and non-standard boxes to be customized. This salt spray corrosion test box can be used to evaluate the salt spray corrosion resistance of materials and their protective layers, as well as the process quality comparison of similar protective layers, and can also be used to evaluate the salt spray corrosion resistance of some products. The equipment can reach any temperature point from normal temperature to 55℃ in the test workspace and keep it constant.
