Where trace oxygen monitoring pays off

Chang Ai analyzers are used across exactly the industries 1368 serves:

- Semiconductor & electronics — protective gas monitoring in reflow and wave soldering, and inert atmosphere control where trace oxygen ruins solder joints and wafer processes.
- Air separation & gas production — verifying N2 and Ar purity to ppm specification before the gas ships.
- Food production — monitoring inert gas and packaging atmospheres where residual oxygen shortens shelf life.
- Petrochemical — oxygen detection in hydrocarbon and inert gas streams for both safety (explosion risk) and process quality.
- Inert gas blanketing — confirming tank and vessel atmospheres stay below the oxygen threshold.

For metallurgy buyers, the same analyzers monitor weld-purge and furnace atmospheres where trace oxygen causes oxidation and embrittlement. *1368 specifies and integrates
