EpRox probes are very reliable also in near stoichiometric conditions. The gas to be investigated is heated up and catalytically decomposed. After reaction the oxygen content is measured at equilibrium and converted.
To ensure constant combustion conditions in the forehearth for stable glass quality also by fluctuating heating values. With the EpRox1000-FH up to 12 measuring points along the forehearth can be monitored with just one probe. After measuring the remaining oxygen of the decomposed premixed gas, the Lambda value as well as the oxygen content in the initial premixed gas is calculated.
