Sulfur Dioxide Test Chamber

SQ-010 Sulfur Dioxide Test Equipment uses sulfur dioxide gas to accelerate corrosion of materials or products in a certain temperature environment, reproducing the damage degree suffered by materials or products within a certain time range. The chamber can be used to assess the ability of materials and their protective layers to resist sulfur dioxide corrosion, as well as the process quality comparison of similar protective layers, and can also be used to assess the ability of certain products to resist sulfur dioxide corrosion. This chamber is suitable for corrosive gas testing of parts, electronic components, metal materials and industrial products, etc.
