Lub neej ua haujlwm ntev npaum li cas ntawm cov electrode ntawm pH meter?
Cov lus nug no feem ntau nug los ntawm ntau tus neeg siv, tab sis nws tsis tuaj yeem teb tau ob peb lo lus. Ua ntej, lub teb chaws tus qauv (ZBN50003-88) qhia txog cov kev cai ntawm electrode "lub neej": "Lub sij hawm lav ntawm electrode: txij hnub tsim khoom cim rau ntawm lub electrode, thaum nws yog unpacked thiab siv nyob rau hauv ib xyoos ntawm kev cia, Nws cov kev ua tau zoo yuav tsum ua tau raws li cov qauv no, tag nrho cov kev cai ntawm tus qauv, thaum lub sij hawm lav, yog tias cov electrode raug pom tias tsis tuaj yeem ua haujlwm ib txwm vim yog cov khoom tsim khoom, cov chaw tsim khoom yuav tsum muaj lub luag haujlwm kho lossis xa rov qab. Nws yog qhov tseeb heev ntawm no tias lub sijhawm lav zoo ntawm lub tshuab electrode yog raws li qhov tseeb tias nws tsis tau siv, lub hauv paus yog tias lub neej ntawm electrode yog ib xyoos, yog li ntau tus neeg feem ntau hais tias lub neej ntawm electrode yog. ib xyoos, qhov tseeb, qhov no tsis yog lawm, ntxiv rau qhov zoo ntawm cov electrode nws tus kheej, kuj tseem muaj teeb meem ntawm kev siv thiab kev txij nkawm, thawj zaug yog siv qhov nruab nrab, tib lub electrode nws yuav tuaj rau hauv kev sib cuag nrog cov xov xwm sib txawv. Qee cov xov xwm tau huv heev, xws li dej kais dej, thiab qee qhov xov xwm muaj zog acid thiab alkali lossis txawm tias kub. Qhov thib ob yog lub sijhawm siv, qee qhov siv qee zaus, thiab qee qhov siv tsis tu ncua ntev. Qhov thib peb yog seb puas yuav ntxuav thiab tswj, yog li ntawm no yuav muaj qhov sib txawv loj. Feem ntau hais lus, yog tias lub tshuab hluav taws xob tsis ua haujlwm nyob rau lub sijhawm luv luv, nws yuav yog tias tus qauv electrode tsis raug xaiv raug lossis tus neeg siv tswj nws tsis raug. Hauv qhov no, cov chaw tsim khoom tsis muaj lub luag haujlwm rau cov nyiaj rov qab. Tau kawg, yog tias cov electrode tau siv, tab sis nws cov tsos tseem zoo, thiab tsis muaj ib qho kev siv tsis zoo, nws yuav yog vim qhov zoo ntawm cov electrode, thiab cov chaw tsim khoom feem ntau yuav tsum tau them rov qab cov nyiaj them poob haujlwm. Raws li rau qee cov electrodes uas thov kom lub neej ntev electrodes, yeej muaj qee qhov teeb meem Yog. Lub sij hawm siv dav dav ntawm electrode yog ib nrab xyoo mus rau ib xyoos, thiab lub sij hawm ntawm kev lag luam pH electrodes nrog kev siv tsis zoo yuav luv dua.
