Ntev npaum li cas cov electrodes ntawm pH meter ntev?
Cov lus nug no feem ntau nug los ntawm ntau tus neeg siv, tab sis nws tsis tuaj yeem teb los ntawm ob peb lo lus yooj yim. Ua ntej ntawm tag nrho cov, lub teb chaws tus qauv (ZBN50003-88) ntawm lub electrode "lub neej" ntawm cov kev cai: "electrode warranty lub sij hawm: los ntawm lub electrode cim nyob rau hauv lub hnub tsim khoom, lub electrode nyob rau hauv ib xyoos ntawm lub sij hawm cia ntawm lub unpacking thiab siv, nws cov kev ua tau zoo yuav tsum ua tau raws li tag nrho cov kev cai ntawm tus qauv no thaum lub sij hawm lav, yog tias nws pom tias cov electrode tsis ua hauj lwm zoo vim yog vim li cas los ntawm cov chaw tsim tshuaj paus, cov chaw tsim tshuaj paus yuav tsum muaj lub luag hauj lwm rau kho los yog xa rov qab cov khoom. electrode rau kev hloov 'Nws yog qhov tseeb heev ntawm no, lub sijhawm lav zoo ntawm cov electrode, yam tsis muaj kev siv lub hauv paus, lub sijhawm ntawm ib xyoos, ntau tus neeg hais lus nyob rau hauv cov nqe lus ntawm lub neej ntawm cov electrode yog ib xyoos, nyob rau hauv ib lub xyoo. Qhov tseeb, qhov no tsis yog qhov tseeb ntawm no ntxiv rau qhov zoo ntawm cov electrode nws tus kheej muaj teeb meem ntawm kev siv thiab kev txij nkawm Ua ntej tshaj plaws, kev siv xov xwm, tib lub electrode yuav sib cuag nrog cov xov xwm sib txawv, qee qhov kev tshaj tawm yog heev huv si, xws li kais dej, ib co xov xwm yog muaj zog acid thiab alkali thiab txawm kub. Qhov thib ob yog siv lub sijhawm, qee qhov siv qee zaus, qee qhov yog siv mus ntev. Qhov thib peb yog seb qhov kev tu thiab tu, yog li yuav muaj qhov sib txawv loj, feem ntau hais lus, ib qho electrode yog tias qhov tsis ua haujlwm ntawm lub sijhawm luv luv, nws muaj peev xwm xaiv cov qauv electrode tsis raug lossis cov neeg siv kev saib xyuas tsis zoo. tsim nyog, qhov xwm txheej no tsis yog lub luag haujlwm rau cov chaw tsim khoom ntawm cov nyiaj rov qab. Tau kawg, yog tias cov electrode tau siv, tab sis qhov zoo li tseem zoo heev, thiab tsis muaj qhov tsis zoo ntawm kev siv tsis zoo, nws yuav yog vim li cas electrode zoo, cov chaw tsim khoom feem ntau yuav yog lub luag haujlwm rau cov nyiaj rov qab. Raws li rau qee cov electrodes hu ua lub neej ntev electrodes, qhov tseeb, muaj qee qhov teeb meem. Kev siv cov electrodes rau ib nrab xyoo mus rau ib xyoos, kev siv cov kev siv tsis zoo ntawm cov khoom siv pH electrodes tej zaum yuav luv dua.
