Ua tib zoo saib rau peb lub ntsiab lus tseem ceeb no kom txuas ntxiv lub neej ntawm lub tshuab hluav taws xob tsis zoo pH meter
Thawj yog qhov kev sim tshuaj ntsuam xyuas
Piv txwv li, nyob rau hauv kev lag luam textile, tib lub electrode yog nyob rau hauv kev sib cuag nrog cov kev ntsuam xyuas sib txawv. Qee qhov kev sim tshuaj yog ib leeg thiab tsis muaj kuab paug. Piv txwv li, nyob rau hauv cov ntaub ntawv dav dav, qee qhov kev sim tshuaj muaj zog acid thiab alkali los yog fluffy thiab oily daws. Nws yog ib qho yooj yim kom luv lub neej kev pab cuam ntawm pH electrode. Piv txwv li, pH meter rau kev ntsuas ib txwm siv tau rau ib xyoos, tab sis pH meter rau nquag kuaj cov kua qaub thiab alkalis tsis tuaj yeem ua haujlwm rau ib nrab xyoo. Cov ntsiab lus tseem ceeb yog sim tib txoj kev daws teeb meem nrog cov cwj mem dej tsis muaj pH ntsuas ntau li ntau tau.
Lub ntsiab lus thib ob yog siv sijhawm
Lub sij hawm ntev tsis siv cov cwj mem dej tsis zoo pH meter los yog siv ntau zaus yuav cuam tshuam rau lub neej ntawm electrode. Piv txwv li, qee lub chaw soj nstuam siv nws ib hnub ib zaug, thiab qee zaum tsis siv nws ib zaug ob peb hnub, thiab qee qhov siv nws tsis nres txhua hnub. Tom qab ntawd cov pH ntsuas uas tau siv ntau zaus thiab tsis tshua siv txhua hnub yuav muaj "lub neej luv". Tsim nyog siv pH electrodes uas "tsis ua haujlwm dhau thiab tsis ua haujlwm" yog txoj hauv kev kom lub neej ntev.
Qhov thib peb yog seb koj puas tau xaiv tus qauv tsis raug ntawm tus cwj mem-hom pH meter
Yog tias cov electrode pom tias tsis raug nyob rau ob peb hnub ntawm kev siv, nws yuav yog tias cov qauv electrode raug xaiv tsis raug lossis cov neeg siv siv nws ua phem. Txawm hais tias qhov zaus ntawm kev siv tsawg heev, tus neeg muag khoom tsis muaj lub luag haujlwm rau kev xa rov qab lossis hloov cov khoom hauv qhov no.
Lwm qhov xwm txheej yog tias cov electrode ntawm lub ntsuas dej tsis zoo pH meter tau tawg sai tom qab siv lossis qhov ntsuas tsis raug, cov ntaub ntawv tsis ruaj khov, thiab cov electrode feem ntau siv, cov tsos zoo li qub, thiab kev saib xyuas txhua hnub yog nruj me ntsis txwv tsis pub siv. ua raws li cov lus qhia. Ces Nws yuav yog qhov teeb meem zoo electrode. Raws li rau qee tus cwj mem dej tsis zoo pH meter electrodes uas thov kom lub neej ntev electrodes, muaj qee qhov teeb meem. Lub sij hawm siv dav dav ntawm lub tshuab hluav taws xob 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.
