Kev tu cov electrode ntawm micro-moisture tester
Electrode yog cov khoom tseem ceeb ntawm cov kab dej ya raws tester, electrode deg paug tuaj yeem ua rau txo qis rhiab heev. Yog li ntawd, kev saib xyuas ntawm electrode ntawm cov kab ya raws ya raws yog qhov tseem ceeb heev.
Thaum lub rhiab heev yog txo, lub electrode yog kis kab mob loj. Daim ntawv tuaj yeem dipped hauv me ntsis acetone los so cov electrode, tab sis yuav tsum tau ceev faj, tab sis kuj yuav tsum tau tos kom lub acetone volatilisation tag ua ntej siv. Los yog cov electrode tuaj yeem muab tso rau hauv dilute nitric acid tov rau 24 teev, tom qab ntawd tshem tawm, yaug nrog dej thiab so nrog cov ntawv lim. Cov electrode kuj tuaj yeem ntxuav nrog cov tshuaj potassium dichromate rau l feeb kom qhib cov electrode. Nyob rau hauv cov xwm txheej tshwj xeeb, xws li cov qauv tos rau kev tshuaj ntsuam xyuas, tsis pub ntxuav lub sij hawm electrode, ces muaj nyob rau hauv ib qho kev daws teeb meem thaum muaj xwm ceev rau cov electrode paug ntawm qhov teeb meem. Nrog cov ntawv xuab zeb zoo heev maj mam rub qhov kawg ntawm electrode, lim ntawv wiped huv si, koj tuaj yeem pom cov nyhuv.
Cov cuab yeej xws li ib lub sij hawm tsis siv, yuav tsum yog electrolytic cell nyob rau hauv Karl Fischer reagent tag nrho cov kab, nyob rau hauv thiaj li yuav zam lub reagent volatilisation tshwm sim los ntawm crystallisation thiab clogging ntawm lub raj, lub electrode swabbing. Nyob rau hauv qhov kev ntsuam xyuas ntawm lub twj paj nruag feem ntau tuaj yeem pom, tus neeg teb xov tooj ntawm cov qauv kev txiav txim siab ntawm qhov kawg ntawm lub hwj chim tawm, kev saib xyuas ntawm qhov ntsuas thiab qhov tseeb ntawm qhov ntsuas yuav tsum yog ze ze rau qhov tsis paub txog qhov teeb meem.
