For Testing the Corrosion Characteristics of Materials

To prove the resistance of the technical products to corrosive gases, Vötsch developed the corrosion test chambers cabinets series VCC³. 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: sulphur 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
  • Compliance with test standards such as IEC 60068-2-60, IEC 60068-2-42/43, ISO 21207 and others
