daws muaj cov lus teb zoo. Nyob rau tib lub sijhawm, lub peev xwm asymmetric tuaj yeem txo qis thiab ruaj khov los ntawm soaking iav electrode. Lub pH meter / acidity meter iav electrode feem ntau tuaj yeem tsau rau hauv dej distilled lossis pH meter / acidity meter 4 tsis muaj tshuaj. Feem ntau nws yog qhov zoo dua los siv pH meter / acidity meter 4 tsis tov. Lub sij hawm soaking yog 8 teev mus rau 24 teev los yog ntev dua, nyob ntawm seb lub thickness ntawm lub teeb iav zaj duab xis thiab cov laus degree ntawm electrode. Nyob rau tib lub sijhawm, cov kua sib txuas ntawm cov khoom siv electrode kuj yuav tsum tau ntub dej. .Vim hais tias yog cov kua hlws ris dries, lub peev xwm ntawm cov kua hlws ris yuav nce los yog ua tsis ruaj tsis khov, lub soaking kua ntawm cov reference electrode yuav tsum tau raws li cov kev siv sab nraud ntawm cov reference electrode, uas yog, 3.3mol / L KCL tov. los yog saturated KCL tov. Lub sijhawm feem ntau yog ob peb teev. Yog li ntawd, rau pH meter / acidity meter composite electrode, nws yuav tsum tau muab tso rau hauv lub pH meter / acidity meter 4 tsis muaj tshuaj uas muaj KCL, kom nws tuaj yeem ua haujlwm ntawm lub iav qhov muag teev thiab cov kua dej sib txuas tib lub sijhawm. . Kev saib xyuas tshwj xeeb yuav tsum tau them rau ntawm no, vim tias yav dhau los, tib neeg siv ib qho pH meter / acidity meter iav electrode rau soak hauv dej deionized los yog pH meter / acidity meter 4 tsis siv tshuaj, thiab tom qab ntawd siv pH meter / acidity meter composite electrode. Siv txoj kev ntub dej zoo li no, txawm tias qee cov lus qhia tsis raug rau kev siv pH meter / acidity meter composite electrode yuav ua raws li cov lus qhia tsis raug. Qhov txiaj ntsig ncaj qha ntawm txoj kev ntub dej tsis raug no yog ua kom lub ntsuas pH nrog kev ua haujlwm zoo. Lub 'meter' / acidity meter composite electrode dhau los ua cov electrode nrog cov lus teb qeeb thiab qhov tsis zoo, thiab lub sij hawm ntub dej ntev dua, qhov ua tau zoo dua, vim tias KCL concentration hauv cov kua dej sib txuas (piv txwv li, hauv cov xuab zeb core) tau txo qis heev. tom qab lub sijhawm so ntev. Qhov kev sib tshuam muaj peev xwm nce thiab ua tsis ruaj khov. Tau kawg, cov electrode yuav rov zoo dua yog tias nws rov qab los rau hauv cov kua dej kom raug rau ob peb teev.
Tsis tas li ntawd, pH meter / acidity meter electrode yuav tsum tsis txhob muab tso rau hauv nruab nrab lossis alkaline tsis daws teeb meem. Kev tso dej mus ntev hauv cov kev daws teeb meem no yuav ua rau pH meter / acidity meter iav membrane tsis teb. Kho pH meter/acidity meter electrode immersion Kev npaj ua kua: nqa ib lub hnab pH meter/acidity meter 4.00 buffer (250ml), yaj hauv 250ml dej ntshiab, ntxiv 56 grams ntawm cov tshuaj analytical ntshiab KCl, cua sov kom zoo, thiab do kom txog thaum nws yaj tag. Muaj lub raj mis electrodes ntawm lub khw. Muaj ob hom dej so, 500ml thiab 50ml. Cov dej ntub dej no muaj cov tshuaj tua kab mob, uas yuav tsis tuaj pwm thiab deteriorate. Lub neej txee yog ib xyoos.
Txhawm rau ua kom lub pH meter / acidity meter compound electrode siv tau yooj yim dua, qee qhov txawv teb pH meter / acidity meter compound electrodes thiab qee cov khoom siv hluav taws xob hauv tsev tau nruab nrog lub hnab yas kaw ntawm lub taub hau ntawm pH meter / acidity meter compound electrode, thiab cov electrode yog tsau rau hauv. Lub taub hau electrode yog tsau rau hauv nws ntev, thiab nws tuaj yeem rub tawm thiab ntxuav thaum siv, uas yooj yim heev. Txoj kev khaws cia no tsis yog yooj yim xwb, tab sis kuj tseem muaj txiaj ntsig zoo los ua kom lub neej ntev ntawm cov electrode, tab sis cov kua dej hauv cov yas vial yuav tsum tsis txhob muaj kuab paug, ua tib zoo hloov.
