Cov pH meter electrodes siv hauv chav kuaj yog tag nrho cov khoom siv hluav taws xob sib xyaw, uas muaj qhov zoo ntawm kev siv yooj yim, tsis cuam tshuam los ntawm oxidizing los yog txo cov tshuaj, thiab ntsuas ceev ceev. Thaum siv, tshem lub tes tsho roj hmab ntawm lub electrode filling chaw nres nkoj thiab lub tes tsho roj hmab hauv qab kawg kom tswj tau qhov sib txawv ntawm qhov sib txawv ntawm cov tshuaj potassium chloride hauv cov electrode. Cov hauv qab no yog cov lus qhia luv luv rau Kev siv thiab kev saib xyuas ntawm pH meter electrodes:
1. Thaum tsis siv cov hluav taws xob sib xyaw, nws tuaj yeem ua tiav hauv 3M potassium chloride tov. Tsis txhob muab tso rau hauv cov kua ntxhua khaub ncaws los yog lwm cov tshuaj absorbent.
2. Ua ntej siv, xyuas lub teeb ntawm lub hauv ntej kawg ntawm lub iav electrode. Raws li ib txwm muaj, lub electrode yuav tsum pob tshab tsis muaj kab nrib pleb; lub teeb yuav tsum tau ntim nrog cov tshuaj tsis muaj npuas.
3. Thaum ntsuas cov kev daws teeb meem nrog cov concentration loj, sim ua kom luv lub sij hawm ntsuas kom ntau li ntau tau, thiab ntxuav nws kom zoo tom qab siv los tiv thaiv cov kua ntsuas los ntawm adhering rau electrode thiab paug cov electrode.
4. Tom qab ntxuav lub tshuab electrode, tsis txhob so lub iav daim nyias nyias nrog cov ntawv lim, tab sis siv cov ntawv lim kom qhuav kom tsis txhob muaj kev puas tsuaj rau cov iav daim nyias nyias, tiv thaiv kev sib kis -, thiab cuam tshuam rau kev ntsuas qhov tseeb.
5. During the measurement, pay attention to the silver-silver chloride internal reference electrode of the electrode should be immersed in the chloride buffer solution in the bulb to avoid the phenomenon of digital jumping in the display part of the electric meter. When using, pay attention to gently shake the electrode a few times.
6. Cov electrode tsis tuaj yeem siv rau hauv cov kua qaub, muaj zog alkali lossis lwm yam kev daws teeb meem corrosive.
7. Nws yog nruj me ntsis txwv tsis pub siv nyob rau hauv dehydrating media xws li kiag li ethanol, poov tshuaj dichromate, thiab lwm yam.
