Noxious gas test chamber

Noxious gas test chamber

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 chamber 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 500 ppb.
 
Gases concentration are monitored with the use of SPM Flex analyser
 
Preferred test duration is 4, 7, 10, 14 or 21 days.
