Kev ua tau zoo ntawm cov cuab yeej, ntxiv rau cov qauv ntawm lub ntsuas nws tus kheej, thiab kev saib xyuas zoo yog qhov sib cais tsis tau, PH meter xws li cov twj paj nruag thiab kev siv ib puag ncig feem ntau cuam tshuam nrog cov tshuaj lom neeg, yog li ntawd, kev saib xyuas tsim nyog yog qhov tsim nyog.
1. Cov khoom siv sab nraud ntawm lub ntsuas hluav taws xob (xws li cov khoom siv hluav taws xob sib txuas) yuav tsum tau khaws cia ntawm qhov kev huv huv siab thiab cov hluav taws xob hluav taws xob yuav tsum tsis txhob raug hloov ntau zaus kom tsis txhob muaj plua plav thiab cov av noo siab.
2. Lub taub hau ntawm cov khoom siv hluav taws xob yuav tsum tsis txhob sib cuag nrog cov av, yog tias pom muaj stained, siv cov paj rwb kho mob maj mam so lub taub hau ntawm electrode, lossis siv 0.1 mol / L dilute hydrochloric acid los ntxuav.
3. Yog tias lub taub hau ntawm cov hluav taws xob sib xyaw yog tawg los yog muaj hnub nyoog (ntau tshaj ib xyoos), nws yuav tsum tau hloov los ntawm cov electrode tshiab, txwv tsis pub cov tshuaj tiv thaiv yuav qeeb thiab txawm tias ua rau muaj kev ntsuas loj.
4. Thaum ntsuas qhov ntsuas nrog cov kev daws teeb meem tsis, qhov kev ntseeg siab ntawm cov tshuaj tsis haum yuav tsum tau ua kom ntseeg tau, vim tias qhov tsis muaj qhov tseeb ntawm cov tshuaj tsis haum yuav ua rau muaj kev ua yuam kev hauv kev ntsuas kev ntsuas.
