Zoo Environmental Resistance Residual Chlorine Sensor

Txoj Cai Ua Haujlwm

Electrolyte thiab osmotic membrane cais cov electrolytic cell thiab cov qauv dej, permeable daim nyias nyias tuaj yeem xaiv rau ClO- nkag;nruab nrab ntawm ob

electrode muaj qhov sib txawv ntawm qhov sib txawv, qhov siv hluav taws xob tam sim no tuaj yeem hloov mus rau hauvresidual chlorineconcentration.

Hauv cathode: ClO^-+ 2H + + 2e^-→ Cl^-+ H₂O

Tom ntej: Cl^-+ Ag → AgCl + e^-

Vim hais tias nyob rau hauv ib tug tej yam kub thiab pH tej yam kev mob, HOCl, ClO- thiab residual chlorine ntawm taag hloov dua siab tshiab kev sib raug zoo, nyob rau hauv txoj kev no yuav ntsuas qhovresidual chlorine.

Technical Index

Kev tu txhua hnub

(1) Xws li kev tshawb pom ntawm tag nrho cov kev ntsuas qhov ntev lub sij hawm teb, membrane rupture, tsis muaj chlorine nyob rau hauv cov xov xwm, thiab hais txog, nws yog tsim nyog los hloov lub membrane, kev kho ntawm electrolyte hloov.Tom qab txhua qhov sib pauv membrane los yog electrolyte, cov electrode yuav tsum tau repolarized thiab calibrated.

(2) Tus nqi ntws ntawm cov qauv dej muaj txiaj ntsig yog khaws cia tas li;

(3) Lub cable yuav tsum khaws cia rau hauv qhov chaw huv, qhuav lossis dej nkag.

(4) Cov cuab yeej tso saib tus nqi thiab tus nqi tiag tiag sib txawv heev lossis tus nqi chlorine seem yog xoom, tuaj yeem qhuav chlorine electrode hauv electrolyte, yuav tsum tau txhaj tshuaj rau hauv electrolyte.Cov kauj ruam tshwj xeeb yog raws li hauv qab no:

Unscrew lub electrode taub hau zaj duab xis lub taub hau (Ceeb toom: kiag li tsis txhob ua puas lub breathable zaj duab xis), drained zaj duab xis ua ntej lub electrolyte, ces tus tshiab electrolyte ncuav rau hauv zaj duab xis ua ntej.Feem ntau txhua 3 lub hlis ntxiv cov electrolyte, ib nrab xyoo rau lub taub hau zaj duab xis.Tom qab hloov cov electrolyte los yog daim nyias nyias lub taub hau, lub electrode yuav tsum tau re-calibrated.

(5) Electrode polarization: lub hau electrode raug tshem tawm, thiab cov electrode txuas nrog lub ntsuas, thiab cov electrode yog ntau tshaj 6 teev tom qab electrode polarized.

(6) Thaum tsis siv qhov chaw ntev ntev yam tsis muaj dej los yog 'meter' ntev, yuav tsum tau tshem tawm cov electrode tam sim, sheathe lub hau tiv thaiv.

(7) Yog tias cov electrode tsis hloov cov electrode.

Dab tsi txhais tau tias Residual Chlorine?

Cov tshuaj chlorine residual yog cov tshuaj chlorine uas tsis tshua muaj nyob hauv dej tom qab qee lub sijhawm lossis lub sijhawm tiv tauj tom qab nws thawj daim ntawv thov.Nws yog ib qho kev tiv thaiv tseem ceeb tiv thaiv kev pheej hmoo ntawm kev kis kab mob microbial tom qab kev kho mob - qhov txiaj ntsig tshwj xeeb thiab tseem ceeb rau kev noj qab haus huv pej xeem.Cov tshuaj chlorine yog ib qho pheej yig thiab yooj yim muaj tshuaj uas, thaum yaj hauv dej ntshiab kom txaus, yuav rhuav tshem cov kab mob feem ntau yam tsis muaj kev phom sij rau tib neeg.Cov tshuaj chlorine, txawm li cas los xij, yog siv raws li cov kab mob raug puas tsuaj.Yog tias muaj cov tshuaj chlorine txaus ntxiv, yuav muaj qee qhov seem hauv dej tom qab tag nrho cov kab mob tau raug rhuav tshem, qhov no yog hu ua dawb chlorine.(Daim duab 1) Cov tshuaj chlorine dawb yuav nyob hauv dej kom txog thaum nws ploj mus rau lub ntiaj teb sab nraud lossis siv los rhuav tshem cov kab mob tshiab.Yog li ntawd, yog tias peb sim dej thiab pom tias tseem muaj qee cov chlorine dawb tshuav, nws ua pov thawj tias cov kab mob txaus ntshai tshaj plaws hauv dej tau raug tshem tawm thiab nws muaj kev nyab xeeb rau haus.Peb hu qhov no ntsuas cov chlorine residual.Kev ntsuas cov tshuaj chlorine seem hauv cov dej yog ib txoj hauv kev yooj yim tab sis tseem ceeb ntawm kev kuaj xyuas tias cov dej uas xa tuaj yog nyab xeeb rau haus.
