Noxious gas test chambers

The test in flowing mixed gas corrosion test allows to determine the corrosive effect of the working and storage environment on electrotechnical components, especially contacts, terminals and connections (considered both separately and as integrated into a component or assembled as a complete equipment).
 
Tested samples are placed in the AirEvent Gas/600/0 and SK1500 chambers under various temperature and humidity conditions, in the atmosphere of single corrosive gas or their mixture: 
  • Cl2
  • SO2
  • NO2
  • H2
Gases are mixed with together depending on the test method and/or Customer requirements. The working range of gases concentration is from 10 to 2700 ppb in case of H2S).
 
Gases concentration are monitored with the use of SPM Flex Honeywell analyser (in case of AirEvent Gas/600/0).
 
Preferred test duration is 4, 7, 10, 14 or 21 days.
