1. Electrochemical oxygen firikwensin
Electrochemical abubuwan gano iskar oxygen ana amfani da su musamman don auna abun cikin iskar oxygen a cikin iska.Waɗannan na'urori masu auna firikwensin an haɗa su a cikin injin RGM don auna ma'auni na isar da iskar oxygen.Suna barin canje-canjen sinadarai a cikin sashin ji, yana haifar da fitarwar lantarki daidai da matakin oxygen.Na'urori masu auna sigina na lantarki suna canza makamashin sinadarai zuwa makamashin lantarki ta hanyar iskar oxygen da rage matakan.Yana ba da fitarwar lantarki zuwa na'urar daidai da adadin oxygen a cikin cathode da anode.Na'urar firikwensin oxygen yana aiki azaman tushen yanzu, don haka ana yin ma'aunin ƙarfin lantarki ta hanyar juzu'in lodi.Fitar da na'urar firikwensin iskar oxygen yayi daidai da adadin yawan iskar oxygen ta firikwensin oxygen.
Fitar halin yanzu na firikwensin lantarki yawanci ana auna shi cikin microamps (a).Wannan halin yanzu yana faruwa lokacin da electrons ke wucewa ta hanyar tsarin iskar oxygen a cikin anode kuma ions suna yaduwa a cikin maganin electrolyte daga tsarin rage oxygen a cathode.
2. Fluorescent oxygen firikwensin
Na'urori masu auna iskar oxygen na gani sun dogara ne akan ka'idar da ke kashe iskar oxygen.Sun dogara da amfani da hanyoyin haske, masu gano haske da kayan haske waɗanda ke amsa haske.Na'urorin firikwensin oxygen na tushen haske suna maye gurbin na'urori masu auna iskar oxygen na lantarki a fagage da yawa.
An dade da sanin ka'idar kashe iskar oxygen kyalli.Wasu kwayoyin halitta ko mahadi suna kyalli (watau suna fitar da makamashin haske) lokacin da aka fallasa su zuwa haske.Duk da haka, idan kwayoyin oxygen suna samuwa, ana canza makamashin hasken zuwa kwayoyin oxygen, yana haifar da ƙananan haske.Ta hanyar amfani da tushen hasken da aka sani, ƙarfin hasken da aka gano ya saba da adadin ƙwayoyin iskar oxygen a cikin samfurin.Sabili da haka, ƙananan ƙarancin haske da aka gano, yawancin kwayoyin oxygen dole ne su kasance a cikin samfurin gas.
A wasu na'urori masu auna firikwensin, ana gano haske sau biyu a cikin sanannen tazarar lokaci.Maimakon auna jumillar kyalli, ana auna raguwar hasken haske akan lokaci (watau quenching fluorescence).Wannan tsarin lokaci na tushen lalacewa yana ba da damar ƙirar firikwensin sauƙi.
Na'urar firikwensin oxygen mai kyalli LOX-02-F firikwensin firikwensin ne wanda ke amfani da hasken kyalli na iskar oxygen don auna matakan oxygen na yanayi.Ko da yake yana da tsari iri ɗaya da nau'i-nau'i 4 kamar na'urori masu auna siginar lantarki na al'ada, ba ya sha oxygen kuma yana da fa'ida na tsawon rayuwa (shekaru 5).Wannan yana sa ya zama mai amfani ga na'urori irin su ƙararrawar tsaro na rage iskar oxygen da ke lura da raguwa kwatsam a cikin matakan oxygen a cikin matsewar iskar da aka adana a cikin iska na cikin gida.
