Debugging ntawm pH meter
Lub pH meter|acidity meter feem ntau siv nyob rau hauv lub chaw soj nstuam muaj cov laus-fashioned domestic Leici 25 acidity meter nrog ib tug tsawg kawg nkaus faib ntawm 0.1 units thiab pHS -2 hom pH meter|acidity meter nrog a faib yam tsawg kawg nkaus ntawm 0.02 units. Tus nqi pH ntawm hom pH ntsuas no|acidity meter Nws yog pom los ntawm tus ntsuas ntsuas. Tus tshiab PH ntsuas ntsuas|acidity meter muaj KL series ntawm lub tuam txhab Kelilong hauv tsev, thiab nws qhov ntsuas kub thiab pH tus nqi tau tso tawm hauv daim ntawv digital ntawm lub vijtsam. Tsis muaj teeb meem dab tsi ntawm pH meter|acidity meter yuav tsum tau calibrated nrog cov txheej txheem buffer tov ua ntej siv.
Ua ntej nyeem phau ntawv qhia ntawm lub ntsuas, qhib lub hwj chim, thiab nruab cov electrodes. Ntxiv cov tshuaj tsis haum nrog tus nqi pH ntawm 7. Nyeem cov pH tus nqi ntawm cov tshuaj raws li cov lus qhia txuas nrog pH ntsuas sib txawv|acidity meters, thiab xyuas pH meter|acidity meter kom qhov kev nyeem ntawv yog tib yam li tus nqi tiag tiag ntawm tus qauv tsis pH7.0 thiab ruaj khov; Tom qab ntawd tshem tawm cov electrode los ntawm kev daws, tshem tawm thiab yaug nrog dej distilled, hloov lub khob me me nrog cov txheej txheem tsis haum ntawm pH 4.01 lossis 0.01, raus lub electrode, thiab rov ua cov kauj ruam saum toj no ua kev nyeem ntawv ruaj khov. Qhov no ua tiav qhov kev ntsuas dual-point; Tom qab calibration, yaug lub electrode thiab beaker nrog dej distilled. Tsis txhob tig lub positioning adjuster tom qab calibration, txwv tsis pub recalibration yuav tsum tau.
