1200-hour Moist Carbon Dioxide-Sulfur Dioxide-air Test Chamber

The SQCO-300 mixed gas corrosion test chamber utilizes sulfur dioxide (SO₂) and carbon dioxide (CO₂) to expedite the corrosion process of materials or products within a controlled temperature environment. It accurately simulates the extent of damage that materials or products endure over a specified duration. This test chamber is instrumental in comparing the quality of protective layers, assessing the corrosion resistance of component coatings, electronic parts, metal materials, electrical and electronic products, as well as industrial items in a mixed gas setting. The SQCO-300 chamber is capable of heating the test space to a predetermined temperature and maintaining it consistently. A precise volume of corrosive gases is introduced into the chamber, and upon reaching the standard concentration, the corrosion test on materials or products is initiated. Specification:
