Muaj kev siv ntawm yaj oxygen meters
Lub tshuab nqus pa oxygen yog siv los saib xyuas cov nqi oxygen yaj nyob rau hauv cov kev daws teeb meem xws li tshuaj chiv, metallurgy, kev tiv thaiv ib puag ncig, tshuaj, biochemistry, khoom noj khoom haus thiab dej phwj kho, kev siv dej phwj hauv nroog, thiab lwm yam. Lub microcomputer hauv lub 'meter' tuaj yeem khaws, suav thiab compensate rau qhov ntsuas dissolved oxygen tus nqi. Tag nrho cov tsis tuaj yeem teeb tsa rau cov ntaub ntawv ntsig txog, xws li qhov siab, salinity, thiab lwm yam. Tsis tas li ntawd, qhov ntsuas no kuj muaj cov yam ntxwv ntawm kev ua haujlwm tag nrho, kev ua haujlwm ruaj khov, thiab kev ua haujlwm yooj yim. Nws yog ib qho cuab yeej zoo tshaj plaws rau kev ntsuas oxygen yaj thiab tswj. Tsis tas li ntawd, lub teeb tom qab ntawm lub ntsuas oxygen yaj kuj tseem siv LCD zaub, nrog kev qhia yuam kev thiab tsis siv neeg qhov kub thiab txias ua haujlwm. Cais tawm 4-20mA tam sim no tso zis, ob txheej ntawm relay tswj, siab thiab qis taw tes ceeb toom, lub zog-down nco, tsis muaj roj teeb thaub qab yuav tsum tau, cov ntaub ntawv tuaj yeem txuag tau, cov khoom no tsim nyog rau kev siv hauv kev lag luam.
Daim ntawv thov kev lag luam ntawm cov pa oxygen yaj tau nthuav dav dav, vim 70% ntawm lub ntiaj teb yog dej, thiab feem ntau ntawm cov khoom hauv tib neeg lub cev kuj yog dej. Nws tuaj yeem pom tias cov dej tseem ceeb npaum li cas hauv tib neeg txoj kev ua neej thiab kev nyob ib puag ncig, thiab xyuas kom meej tias cov khoom siv dej siv hauv lub neej txhua hnub Kev haus dej kuj tseem ceeb heev hauv lub neej.
Yog li ntawd, tam sim no, yaj oxygen meters tau siv rau hauv ntau qhov chaw. Thaum cov neeg ua haujlwm kuaj cov dej, cov yeeb yaj kiab saum toj kawg nkaus ntawm cov pa oxygen meter sensor tau npog nrog txheej fluorescent dye. Thaum lub teeb hluav taws xob luv luv ua rau lub teeb fluorescent dye, fluorescent zas xim yuav tawm lub teeb ntev-ntev thaum nws rov qab mus rau hauv av los ntawm lub xeev kev ntxhov siab. Lub teeb liab yog lub teeb liab kuaj. Qhov concentration ntawm cov pa oxygen yaj tuaj yeem paub los ntawm kev sim lub sijhawm ntawm lub teeb liab. Qhov siab dua qhov concentration ntawm yaj oxygen, lub sijhawm luv ntawm lub teeb liab.
Kev siv thiab kev saib xyuas ntawm yaj oxygen meter electrodes
Thaum ntsuas, cov electrode yuav tsum tau muab ntxuav ua ntej hauv dej distilled (los yog dej deionized) thiab qhuav nrog cov ntawv lim kom tsis txhob muaj impurities los ntawm kev coj mus rau hauv cov kua ntsuas. 1/3 ntawm cov electrode yuav tsum tau muab tso rau hauv cov tshuaj uas ntsuas. Thaum tsis siv cov electrode, nws yuav tsum tau ntxuav thiab muab tso rau hauv lub tes tsho tiv thaiv nrog 3.5 mol ntawm cov tshuaj potassium chloride, los yog cov electrode yuav tsum tau muab tso rau hauv lub thawv nrog 3.5 mol ntawm cov tshuaj potassium chloride.
Xyuas seb lub davhlau ya nyob twg thaiv puas qhuav. Yog tias muaj cov stains, thov so nws nrog cawv cawv thiab tshuab ziab ua ntej siv.
Kev tso dej mus sij hawm ntev hauv dej distilled lossis cov ntsiab lus protein yuav tsum zam, thiab kev sib cuag nrog cov roj silicone yuav tsum zam.
Yog hais tias cov electrode tau siv ntev, nws cov iav zaj duab xis yuav ua tau translucent los yog muaj sediments txuas. Hauv qhov no, nws tuaj yeem ntxuav nrog dilute hydrochloric acid thiab yaug nrog dej.
Cov electrode tau siv ntev heev thiab thaum ntsuas qhov yuam kev tshwm sim, nws yuav tsum tau ntsuas nrog lub ntsuas. Ua kev kho.
Thaum Hetai yaj oxygen meter electrode tau khaws cia thiab khaws cia raws li qhov saum toj no thiab tseem tsis tuaj yeem ntsuas thiab ntsuas, nws txhais tau tias cov electrode ua tsis tiav. Thov hloov lub electrode.,
