二氧化硫鹽霧試驗機（又稱二氧化硫腐蝕試驗箱）適用于對金屬材料的防護、零部件電子器件及工業產品等進行回還腐蝕試驗，迅速方便地重現噴涂與與未處理過后金屬表面的腐蝕過程

抗腐蝕pvc板整體壓制成型，無滲漏。箱蓋和箱體之間采用水密封結構，無氣體溢出。箱蓋采用透明材料地到箱內測試物品的試驗狀況。配有雙重氣體過濾裝置，保證排出室外的空氣不會污染環境。線路控制板及其它元氣件均固定在便于檢查和維護的位置。

Anti-corrosive PVC plate is formed integrally through prssing 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. It has been equipped with double air filter to ensure tat the emission gas brings no contamination to environment. Wired control board and other electrical components are positioned in certain places for easy check and maintedance.
