Carbon Dioxide Sulfur Dioxide Spray Chamber

Name: Carbon Dioxide Sulfur Dioxide Spray Chamber
Brand: Xi'an LIB Environmental Simulation Industry

The carbon dioxide sulfur dioxide spray chamber simulates the influence of acidic corrosive gases on material erosion in an atmospheric polluted environment. In a closed workroom, a certain concentration of SO₂ and/or CO₂ is injected, combined with temperature and humidity control, to simulate the corrosive effects of industrial waste gas, acid rain, urban atmosphere and other environments on the material surface. Other various gases, such as Cl₂, H₂S, etc., can be expanded or combined as needed.

Temperature Range：15 ℃ ～ 80 ℃

Humidity Range：30% ~ 98% RH

SO2 Concentration：100 ~500 ppb± 20 ppb (Adjustable)

Air Change Rate ：3~10times /h

Features and Benefits of Carbon Dioxide Sulfur Dioxide Spray Chamber

1. The multi-gas composite corrosion environment simulation not only supports the individual or combined testing of SO₂ / CO₂, but also can be expanded to include gases such as Cl₂, NH₃, and H₂S.

2. The temperature and humidity range is wide and precisely controlled. The temperature control range is 15℃ to 80℃, and the humidity range is 50 to 98%RH, with accuracies of ± 0.5 ℃ and ±2.5%RH respectively.

3. High-precision flowmeters monitor and control gas flow in real time, and provide real-time feedback to achieve dynamic concentration adjustment of gas. The gas control accuracy can reach ±1%, ensuring stable gas release and uniform distribution.

4. High safety, double-sealed cabin door design,316 stainless steel workroom material, suitable for strong acid and strong corrosion environments. Toxic gas after the dilution test of the NaOH solution tank.
