Lub pH meter electrodes ntev npaum li cas?
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) teev "lub neej" ntawm electrodes: "Lub sij hawm lav ntawm electrodes: Pib txij hnub tsim khoom cim rau ntawm lub electrode, thaum unpacked thiab siv nyob rau hauv lub sij hawm cia ntawm ib xyoos, nws kev ua tau zoo yuav tsum ua raws li qhov kev qhia tshwj xeeb no txhua qhov kev xav tau ntawm tus qauv thaum lub sijhawm lav, yog tias nws pom tias cov khoom siv hluav taws xob tsis tuaj yeem ua haujlwm tau zoo vim yog cov chaw tsim khoom ua txhaum, cov chaw tsim khoom yuav tsum muaj lub luag haujlwm rau kev kho lossis xa rov qab hais tias lub sij hawm lav zoo ntawm cov electrode yuav tsum tsis txhob siv kom txog rau thaum nws tau siv lub hauv paus yog tias lub sij hawm yog ib xyoos, yog li ntau tus neeg feem ntau hais tias lub neej ntawm electrode yog ib xyoos. Ntxiv nrog rau qhov zoo ntawm cov electrode nws tus kheej, kuj tseem muaj qhov 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, xws li cov kais dej , thiab qee qhov xov xwm muaj zog acid, alkali lossis txawm tias kub. Ib qho yog siv sijhawm, qee qhov siv qee zaus, thiab qee qhov siv tsis tu ncua ntev. Qhov thib peb yog seb nws puas yog ntxuav thiab khaws cia, yog li 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 raug xaiv tsis raug lossis tus neeg siv tsis tswj nws kom raug. Hauv qhov no, cov chaw tsim khoom tsis muaj lub luag haujlwm rau cov nyiaj rov qab. Tau kawg, yog tias cov electrode tseem zoo txawm tias siv, thiab tsis muaj cov cim ntawm kev siv, nws yuav yog vim qhov zoo ntawm cov electrode, thiab cov chaw tsim khoom feem ntau yuav yog lub luag haujlwm rau cov nyiaj rov qab. Raws li rau qee cov electrodes uas tau lees tias yog lub neej ntev electrodes, muaj qee qhov teeb meem tiag tiag. .Lub sij hawm siv ntawm electrodes yog ib nrab xyoo mus rau ib xyoos, thiab lub sij hawm ntawm kev lag luam PH electrodes nrog kev siv tsis zoo tej zaum yuav luv.
