Dab tsi yog xoom drift ntawm pH meter thiab yuav daws nws li cas!
Dab tsi yog xoom drift ntawm pH meter thiab yuav daws nws li cas! Qhov teeb meem ntawm xoom drift hauv pH meters ua ntej yuav tsum muaj kev nkag siab ntawm xoom drift. Muaj ntau yam uas cuam tshuam rau xoom drift hauv cov ntsuas hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv kev sib txuas ncaj qha amplifiers, uas nyuaj rau kev kov yeej qhov cuam tshuam loj ntawm xoom drift. Thaum cov khoom siv hluav taws xob hloov pauv hloov pauv, lub xeev kev ua haujlwm ntawm cov khoom siv amplification hloov pauv, thiab cov khoom siv hluav taws xob txuas ntxiv sib txawv nrog qhov ntsuas kub thiab lub sijhawm ua haujlwm. Thaum lub tswv yim yog xoom, muaj qhov hloov pauv hauv cov zis, uas yog, xoom drift. Ib zaug ntxiv, nws yog ib qho tseem ceeb los txheeb xyuas lub hauv paus ntawm qhov teeb meem. Muaj ntau qhov teeb meem tseem ceeb ntawm pH electrode, xws li electrode scaling ua rau qhov tsis txaus ntseeg ntawm cov electrodes, ua rau muaj kev cuam tshuam, kev cuam tshuam rau electromagnetic ntev, thiab polarization ntawm electrodes.
Muaj ntau txoj hauv kev los daws qhov kev xav los ntawm xoom drift:
1. Txais kev tswj fais fab,
2. Txais AC amplification Circuit Court
3. Dynamic input impedance
Kev daws rau kev ruaj ntseg thiab xoom drift ntawm industrial pH ntsuas thiab kuaj pH ntsuas
1. Siv cov kev tawm tswv yim tsis zoo Circuit Court. Txhawm rau kom tsis txhob xoom drift thiab txhim kho kev ruaj ntseg, cov amplifiers siv nyob rau hauv pH meters tag nrho siv cov kev tawm tswv yim tsis zoo. Kev lees txais DC cov lus tawm tswv yim tsis zoo tuaj yeem tsis tsuas yog txhim kho cov tswv yim impedance ntawm lub ntsuas, tab sis kuj txhim kho nws txoj kev ruaj ntseg, kom qhov rhiab heev thiab ntau yam ntawm cov cuab yeej tsis cuam tshuam los ntawm kev hloov pauv hauv cov khoom siv hluav taws xob.
2. Kev xaiv thiab txij nkawm ntawm pH electrodes. Lub pH meter composite electrode yog ib feem tseem ceeb los xyuas kom meej qhov ntsuas qhov tseeb. Cov electrodes zoo heev yuav tsum raug xaiv los tiv thaiv kev cuam tshuam ntawm ntau yam tshuaj, qhov kub thiab txias, kev co thiab lwm yam kom muaj kev ruaj ntseg. Piv txwv li, tom qab kuaj hauv cov qauv nplaum, rov ua dua yuav tsum tau ua kom tshem tawm cov seem seem ntawm cov kua nplaum uas ua rau cov electrode thiab zam qhov txo qis los ntawm electrode's npuas zaj duab xis, uas tuaj yeem ua rau qhov ntsuas tsis ua haujlwm.
