Sulfur Dioxide Spray Chamber

Sulfur Dioxide Spray Chamber are widely applied to the accelerated corrosive testing of the protective layer from metallic materials, as well as parts, electrical components and industrial products. It can reproduce the corrosion process happened to the painted or untreated metal surface. Therefore it can be used to perform various kinds of corrosion test in according to relevant standards, such as ISO6988-1985.

Anti-corrosive CPVC plate is formed integrally through pressing and with no leakage.The space between tank lid and tank body is water sealed with no air leaking.While  the lid, which is made of transparent material, allows you to observe the testing items inside clearly to know the status.Sulfur Dioxide Spray Chamber has been equipped with double air filter  ensure that the emission gas brings no contamination to environment. Wired control board and other electrical components are positioned in certain places for easy check and maintain.
