Control of pure gases and gas mixtures
General
OZR 8000 Trace Oxygen Analyser meets the requirements of industrial gas production and thermal treatment industries.
Principle
Measuring principle
–The oxygen in the sample gas diffuses from the sample side of the ZrO2 cell through to the outside (ambient), thereby a potential gradient exists which is measured via the inner/outer electrodes.
–The change in the potential gradient is proportional to the change in concentration of oxygen present in the sample gas
–The reference value is always ambient air.
