VCC3 test chambers for testing the corrosion characteristics of materials

The VCC3 enables an exact dosage of the corrosive gases with a climate conditioned air volume. The main constituents of the corrosive, atmospheric trace elements are: sulfur dioxide (SO2), nitrogen oxide (NOx), hydrogen sulphide (H2S) and chlorine gas (CL2).

Features corrosive gas test system

• Gas dosing with thermal mass flow controller, concentration ranges from ppb to ppm
• Inner test cabinet with connection for gas sampling and entry port NW 50mm
• Air exchange rate in inner test cabinet can be set between one and four per hour
• Door with window included in basic equipment
• Specimen can be observed (inner test cabinet is made of acrylic glass (PMMA))
• Up to four gasses can be dosed simultaneously
• Inner test cabinet, shelf and door are made of acrylic glass
• Pressure monitoring between inner test cabinet and outside as a safety feature
