UL 50E 1200-Hour Moist Carbon Dioxide-Sulfur Dioxide-Air Test Chamber

The SQCO-300 mixed gas corrosion test chamber employs sulfur dioxide (SO₂) and carbon dioxide (CO₂) gases to accelerate corrosion processes on materials and products within controlled temperature environments. This equipment replicates material degradation levels occurring over extended timeframes, enabling comparative analysis of protective layer quality and corrosion resistance evaluation for components, electronic elements, metal substrates, electrical products, and industrial materials exposed to mixed gas conditions.

The SQCO-300 maintains precise thermal regulation within the test workspace, introducing calibrated volumes of corrosive gases until achieving standardized concentration levels for material corrosion testing.
