Ntev npaum li cas cov electrodes ntawm pH meter yuav kav ntev?
Cov lus nug no feem ntau nug los ntawm ntau tus neeg siv, tab sis nws tsis yog ib yam uas tuaj yeem teb tau ob peb lo lus xwb. Ua ntej, qhia txog cov kev cai ntawm lub teb chaws tus qauv (ZBN50003-88) ntawm "lifespan" ntawm electrodes: "Lub sij hawm warranty ntawm electrodes: los ntawm hnub tsim khoom cim rau ntawm lub electrode, thaum unpacked thiab siv nyob rau hauv ib xyoos ntawm kev cia khoom. , nws qhov kev ua tau zoo yuav tsum ua kom tau raws li txhua qhov kev xav tau ntawm tus qauv no Thaum lub sijhawm lav, yog tias cov khoom siv hluav taws xob tsis tuaj yeem ua haujlwm zoo vim yog vim li cas, cov chaw tsim khoom yuav tsum muaj lub luag haujlwm kho lossis hloov. " Qhov no yog qhov tseeb heev. Lub sijhawm lav ntawm electrodes yog nyob ntawm qhov chaw uas lawv tsis tau siv, nrog rau lub sijhawm ntawm ib xyoos. Yog li ntawd, ntau tus neeg feem ntau hais tias lub neej ntawm electrodes yog ib xyoos, uas yog qhov tsis raug. Ntxiv rau qhov zoo ntawm cov electrode nws tus kheej, kuj tseem muaj teeb meem ntawm kev siv thiab kev saib xyuas. Ua ntej, kev siv xov xwm yog qhov tsim nyog. Tib lub electrode yuav tuaj rau hauv kev sib cuag nrog cov xov xwm sib txawv. Qee qhov kev tshaj tawm yog huv heev, xws li cov dej kais dej, thaum lwm tus yog cov kua qaub, muaj zog alkalis, lossis txawm tias qhov kub thiab txias ** Nws yog lub sijhawm siv, qee qhov siv qee zaus, qee qhov siv txuas ntxiv mus ntev. Qhov thib peb qhov teeb meem yog seb puas yuav ntxuav thiab tswj nws, yog li yuav muaj qhov sib txawv tseem ceeb. Feem ntau hais lus, yog tias lub tshuab hluav taws xob tsis ua haujlwm nyob rau lub sijhawm luv luv, nws yuav yog vim kev xaiv cov qauv electrode tsis raug lossis kev saib xyuas tsis raug los ntawm tus neeg siv. Hauv qhov no, cov chaw tsim khoom tsis muaj lub luag haujlwm rau cov nyiaj rov qab thiab kev them nyiaj. Tau kawg, yog tias cov electrode tau siv tab sis tseem zoo li tsis muaj cov cim qhia ntawm kev siv, nws yuav yog vim qhov zoo ntawm cov electrode, thiab cov chaw tsim khoom feem ntau yog lub luag haujlwm rau cov nyiaj rov qab thiab kev them nyiaj. Raws li rau qee cov electrodes uas thov kom muaj lub neej ntev, muaj qee qhov teeb meem. Lub sijhawm siv dav dav ntawm electrodes yog rau lub hlis mus rau ib xyoos, thiab cov khoom siv pH electrodes nrog cov kev siv tsis zoo yuav muaj sijhawm siv luv dua.
