Determining oxygen content in non-combustible gases from combustion installation involves removing test gas, feeding to electrode of solid electrolyte, and correcting according to changes in temperature and/or pressure

摘要

Determining the oxygen content in non-combustible gases (100) from a combustion installation involves removing a defined amount of test gas (102) per time unit from the gas being investigated using a capillary (9) and a low pressure formed in a cladding tube (7), feeding to an electrode (5) of a solid electrolyte (3) outside a housing, acquiring changes formed by temperature and/or pressure influences and correcting. An independent claim is also included for a measuring device used in the above process.
