Vim li cas thiaj yuav tsum tau pH electrode calibrated tsis tu ncua?
Tom qab pH electrode siv rau lub sijhawm, lub peev xwm asymmetric yuav hloov pauv zoo heev, yog li nws yuav tsum tau ntsuas tsis tu ncua.
Tus naj npawb ntawm cov qauv pH electrode nyob ntawm tus qauv, kev ua haujlwm ntawm electrode thiab qhov tseeb ntawm kev ntsuas. Rau kev ntsuas qhov tseeb (tsawg dua lossis sib npaug rau ±0.03PH), nws yuav tsum tau ntsuas lub sijhawm; rau kev ntsuas dav dav (tsawg dua lossis sib npaug rau ± 0.1PH), nws tuaj yeem siv tsis tu ncua rau ob lub lis piam lossis ntev dua tom qab ib qho kev ntsuas. Tsuav qhov kev ntsuas qhia tau hais tias pH yog qhov tseeb, nws tsis tas yuav tsum tau nquag electrode calibration.
Thaum unpacked thiab siv nyob rau hauv lub sij hawm siv tau, nws ua tau raws li tag nrho cov kev cai ntawm tus qauv no. Thaum lub sij hawm lav, yog tias cov electrode pom tias tsis ua hauj lwm ib txwm yog vim li cas cov chaw tsim khoom, cov chaw tsim khoom yuav tsum muaj lub luag haujlwm kho lossis rov qab los. Yog li ntawd, lub sijhawm lav zoo ntawm cov electrode yog nyob ntawm qhov chaw uas nws tsis tau siv, thiab lub sijhawm yog ib xyoos. Feem ntau hais lus, lub neej kev pab cuam ntawm electrode yog ib xyoos, uas tsis yog lawm.
Kev pabcuam lub neej ntawm cov electrode muaj ntau yam ua rau nruab nrab, thiab kev pabcuam lub neej ntawm cov xov xwm sib txawv yog txawv kiag li. Hauv ntau qhov mob hnyav, nws tsuas yog siv tau 2 lub hlis xwb. Thiab qee qhov kev tshaj tawm zoo dua yog siv li ntawm ib xyoos lossis ntev dua. Yog li ntawd, peb xav kom cov neeg siv sim yuav cov khoom siv hluav taws xob uas tsim los ntawm cov chaw tsim khoom ze tshaj plaws ntawm lub sijhawm kawg! Lub sijhawm cia luv luv, qhov siv tau zoo dua!
Lub neej ua haujlwm ntev npaum li cas ntawm pH electrode?
Hais txog lub neej ntawm cov electrode, lub teb chaws tus qauv (ZBN50003-88) qhia tias "lub sij hawm lav ntawm lub electrode: txij li hnub tsim khoom ntawm lub electrode, thaum nws yog unpacked thiab siv nyob rau hauv ib xyoos ntawm kev siv, nws Kev ua tau zoo ua tau raws li tag nrho cov kev cai ntawm tus qauv no, yuav tsum tau ua. Thaum lub sij hawm lav, yog tias cov electrode pom tias tsis tuaj yeem ua haujlwm ib txwm vim yog cov khoom tsim khoom, cov chaw tsim khoom yuav tsum muaj lub luag haujlwm kho lossis xa rov qab. " Yog li ntawd, lub sijhawm lav zoo ntawm electrode yog nyob ntawm qhov chaw uas nws tsis tau siv, thiab lub sijhawm yog ib xyoos. Feem ntau hais lus, kev pab cuam lub neej ntawm electrodes yog ib xyoos, uas tsis yog lawm. Kev pabcuam lub neej ntawm cov electrode muaj ntau yam ua rau nruab nrab, thiab kev pabcuam lub neej ntawm cov xov xwm sib txawv yog txawv kiag li. Hauv ntau qhov mob hnyav, nws tsuas yog siv tau 2 lub hlis xwb. Thiab qee qhov kev tshaj tawm zoo dua yog siv li ntawm ib xyoos lossis ntev dua. Yog li ntawd, peb xav kom cov neeg siv sim yuav cov electrodes uas tsim los ntawm cov chaw tsim khoom ze tshaj plaws hauv lub sijhawm tshiab! Lub sijhawm cia luv luv, qhov siv tau zoo dua!
