Analizador de trazas de Oxígeno - OZR 8000
Control of pure gases and gas mixtures
General
OZR 8000 Analizador de trazas de Oxígeno meets the requirements of industrial gas production y thermal treatment industries.
Principio
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.
