DOG-209FA hom oxygen electrode tau txhim kho los ntawm yav tas los yaj cov pa electrode, hloov diaphragm rau hauv ib lub mesh hlau daim nyias nyias, muaj kev ruaj ntseg thiab kev ntxhov siab, tuaj yeem siv rau hauv ib puag ncig hnyav dua, kev tu ntim me me, haum rau kev kho dej hauv nroog, industrial pov tseg dej kho, aquaculture thiab ib puag ncig saib xyuas thiab lwm yam kev ntsuas tas li ntawm cov pa oxygen yaj.

Dissolved oxygen yog ib qho kev ntsuas ntawm cov pa oxygen uas muaj nyob hauv dej.Cov dej noj qab haus huv uas tuaj yeem txhawb nqa lub neej yuav tsum muaj cov pa oxygen yaj (DO).
Dissolved Oxygen nkag mus rau hauv dej los ntawm:
ncaj qha nqus los ntawm huab cua.
ceev ceev txav los ntawm cua, nthwv dej, tam sim no los yog mechanical aeration.
dej cog lub neej photosynthesis raws li ib tug by-product ntawm txheej txheem.
Ntsuas cov pa oxygen yaj hauv dej thiab kev kho mob kom tswj tau cov qib DO, yog qhov tseem ceeb hauv ntau hom kev kho dej.Thaum yaj cov pa oxygen yog qhov tsim nyog los txhawb lub neej thiab kev kho cov txheej txheem, nws kuj tuaj yeem ua rau muaj kev puas tsuaj, ua rau oxidation ua rau cov khoom puas thiab cuam tshuam cov khoom.Dissolved oxygen cuam tshuam:
Quality: Lub DO concentration txiav txim siab qhov zoo ntawm cov dej.Yog tias tsis muaj DO txaus, cov dej hloov tsis zoo thiab tsis zoo cuam tshuam rau qhov zoo ntawm ib puag ncig, dej haus thiab lwm yam khoom.
Kev Ua Raws Cai: Ua raws li cov cai, cov dej khib nyiab feem ntau yuav tsum muaj qee yam ntawm DO ua ntej nws tuaj yeem tso tawm mus rau hauv cov kwj dej, pas dej, dej lossis hauv dej.Cov dej noj qab haus huv uas tuaj yeem txhawb nqa lub neej yuav tsum muaj cov pa oxygen yaj.
Kev Tswj Xyuas Txheej Txheem: DO qib yog qhov tseem ceeb los tswj kev kho cov dej khib nyiab, nrog rau theem biofiltration ntawm cov dej haus.Hauv qee cov ntawv thov kev lag luam (xws li kev tsim hluav taws xob) ib qho DO ua rau muaj kev puas tsuaj rau lub tshuab hluav taws xob thiab yuav tsum tau muab tshem tawm thiab nws cov concentrations yuav tsum nruj nruj.
