Yuav ua li cas tswj lub ntsuas acidity / PH meter zoo
Lub pH meter yog ib qho cuab yeej siv thiab khoom siv, feem ntau yog siv los ntsuas pH tus nqi ntawm cov kua nruab nrab. Nrog rau qhov sib thooj ion xaiv electrode, nws kuj tuaj yeem ntsuas MV tus nqi ntawm ion electrode peev xwm. Nws yog dav siv hauv kev lag luam, kev ua liaj ua teb, kev tshawb fawb tshawb fawb, kev tiv thaiv ib puag ncig thiab lwm yam. Cov cuab yeej tseem yog cov cuab yeej tshuaj xyuas tseem ceeb rau QS thiab HACCP ntawv pov thawj hauv cov chaw tsim khoom noj thiab cov dej haus. Yog li, yuav ua li cas tswj cov acidity meter zoo?
Kev saib xyuas zoo ntawm acidity meter yuav tsum pib los ntawm cov hauv qab no:
1. Thaum ntsuas, cov hlau lead ntawm cov electrode yuav tsum tau khaws cia, txwv tsis pub nws yuav ua rau kev ntsuas tsis ruaj khov.
2. Cov khoom siv hluav taws xob siv los ntawm cov cuab yeej siv yuav tsum tau ua kom zoo.
3. Cov cuab yeej siv MOS integrated Circuit Court, yog li cov hlau Circuit Court yuav tsum tau zoo hauv av thaum tu.
4. Thaum ntsuas lub ntsuas ntsuas nrog cov tshuaj tsis haum, qhov kev ntseeg siab ntawm cov tshuaj tsis haum yuav tsum tau ua kom ntseeg tau, thiab cov tshuaj tsis raug cai tsis tuaj yeem sib xyaw, txwv tsis pub nws yuav ua rau qhov kev ntsuas tsis raug.
5. Cov khoom siv kawg ntawm qhov ntsuas yuav tsum tau ua kom qhuav thiab huv si. Thaum lub ntsuas ntsuas tsis siv, ntxig Q9 luv-circuit plug rau hauv lub qhov (socket) kom tsis txhob muaj plua plav thiab dej vapor nkag mus.
6. Lub tshuab hluav taws xob electrode yog tsim los siv nrog lwm cov electrodes, thiab nws yuav tsum tau tiv thaiv los ntawm ya raws thiab plua plav ntawm lub sijhawm zoo tib yam.
Ntev npaum li cas cov electrode ntawm pH meter dav dav siv tau?
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. Thawj 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 tsim txom, 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, muaj tiag tiag ib co teeb meem. Lub sijhawm siv hluav taws xob dav dav yog ib nrab xyoo mus rau ib xyoos, thiab lub sijhawm ntawm kev lag luam pH electrodes nrog cov kev siv tsis zoo yuav luv dua.
