UmGaqo wokuSebenza
I-Polarographic echithwe i-oxygen sensors isebenza ngokusekelwe kwimigaqo ye-electrochemical, ngokuyinhloko isebenzisa i-Clark electrode. I-sensor iqukethe i-cathode yegolide, i-anode yesilivere, kunye ne-electrolyte ethile, zonke zifakwe kwi-membrane ekhethiweyo ekhethiweyo.
Ngexesha lokulinganisa, i-oxygen isasazeka kwi-membrane kwi-sensor. Kwi-cathode (i-electrode yegolide), i-oksijini iyancipha, ngelixa i-anode (i-electrode yesiliva), i-oxidation iyenzeka. Le nkqubo ivelisa i-diffusion yangoku ngokulinganayo kwi-concentration ye-oksijini enyibilikileyo kwisampulu, eyenza umlinganiselo ochanekileyo.
