Kev npaj ua ntej siv ph meter
1. Ntxuav lub electrode nrog triple distilled dej ua ntej siv lub pH meter, thiab ceev faj tsis txhob ua txhaum lub iav electrode.
2. Npaj muab cov tshuaj NAOH thiab HCL tov rau kev hloov kho ntawm lub platform pH meter.
3. Tshem tawm cov tshuaj pH ruaj khov (PH=70) hauv lub tub yees thiab muab tso rau ntawm lub platform.
4. Qhib lub ntsuas pH, kho tus nqi pH, nias tus yuam sij ︿﹀ xaiv PH thiab CAL xaiv, xaiv cov khoom CAL, kho thiab ntxig rau hauv PH tov (PH=7.{{2 } }), nias tus yuam sij " " xaiv cov ntaub ntawv tus nqi rau 7.
5. Ntxig lub iav electrode rau hauv cov tshuaj yuav tsum tau kuaj, tom qab ntawd muab tso rau hauv lwm lub electrode, thiab do cov kua kom zoo (ceeb toom: tsis txhob tawg lub iav electrode).
6. Thaum siv lub tshuab hluav taws xob ntawm pH meter, yuav tsum tau them nyiaj rau kev tiv thaiv ntawm lub voj voog. Thaum tsis ntsuas pH tus nqi, cov tswv yim ntawm pH meter yuav tsum luv luv kom tsis txhob muaj kev puas tsuaj rau pH meter.
7. Lub qhov (socket) iav electrode ntawm lub ntsuas pH yuav tsum tau ua kom huv si, huv si thiab qhuav, thiab yuav tsum tsis txhob raug cov pa phem xws li ntsev tsuag thiab kua qaub pos. Nyob rau tib lub sij hawm, nws yog nruj me ntsis txwv tsis pub muaj cov tshuaj aqueous ntawm lub iav electrode qhov (socket) kom tsis txhob muaj cov input siab impedance ntawm pH meter.
8. Ceev faj ntxiv cov tshuaj NAOH thiab HCL tov thaum tus nqi pH koj xav tau tsis ncav cuag.
9. Ceev faj kom tsis txhob siab tshaj qhov yuav tsum tau ntim ntim thaum ntxiv cov kua.
