Mitar iskar oxygen da aka narkar da haske shine babban madaidaici, kayan aiki mai ƙarfi da ake amfani da shi don auna narkar da iskar oxygen a cikin ruwa. Ka'idar aikinsa ta dogara ne akan hulɗar abubuwa masu kyalli da oxygen, kuma yana da aikace-aikace masu yawa, ciki har da kula da muhalli, kiwo, kula da ruwa, bincike na ruwa da bincike na dakin gwaje-gwaje. Saboda wannan dalili, narkar da mita oxygen mai walƙiya yana taka muhimmiyar rawa wajen kiyaye ma'aunin muhalli na ruwa da kuma kare albarkatun ruwa.
Lianhua šaukuwa mai kyalli narkar da iskar oxygen kayan aiki LH-DO2M (V11) yana amfani da bakin karfe cikakken rufaffiyar lantarki, tare da ƙimar hana ruwa na IP68. Yana da sauƙi a yi aiki kuma shine mataimaki mai ƙarfi a cikin gano najasa, ruwan datti da ruwan dakin gwaje-gwaje. Ma'auni na narkar da iskar oxygen shine 0-20 mg / l. Babu buƙatar ƙara electrolyte ko gyare-gyare akai-akai, wanda ke rage farashin kulawa sosai.
