₂Ukuhlaziywa kwezakhi ezimbiliIngabe ukuhlaziya okuphelele okungakwazi ukubona ngasikhathi sinye okuqukethwe i-oxygen, i-carbon monoxide kanye nokusebenza kahle kwenqubo yokuhlanganisa. It can monitor the oxygen content and carbon monoxide content in the flue gas during or after the combustion of boilers, furnaces, and kilns.

₂Ukuhlaziywa kwezakhi ezimbili, abasebenzisi bangagcina amandla amaningi nokulawula ukuphuma kwegesi.

Lapho u-E ungumuntu oxygen, r yigesi njalo, i-T iyinani lokushisa eliphelele, po₂₂

Uma ingcindezi yakwa-Atmospheric ejwayelekile yomoya owodwa futhi ukugxila kwe-oxygen emoyeni kungu-21%, ifomula lingenziwa lula ku:
