Kev sib raug zoo thiab kev sib txawv ntawm ib qho ion meter, pH meter, thiab acidity meter
Acidity yog hais txog lub ntsiab lus ntawm tag nrho pH tus nqi ntawm cov khoom uas tuaj yeem ua rau cov hauv paus muaj zog hauv dej: PH{{{0}}lg{H ntxiv } 1. Qhov ntau dua tus nqi ntawm acidity, lub acidity ntawm lub zog ntau dua. daws. 2. Tsis muaj teeb meem ntawm qhov kub thiab txias, nruab nrab Lub nruab nrab tov AG yog ib txwm 0. Qhov sib txawv yog tias nws yog ib txwm xav tias pH ntawm qhov nruab nrab ntawm 25 degrees Celsius yog 7, thiab pH ntawm cov tshuaj nruab nrab ntawm lwm qhov kub tsis yog 7. Tsis tas li ntawd, tus nqi ntawm acidity AG yog R, thaum. tus nqi ib txwm muaj ntawm pH yog 0 ~ 14.
Lub ntsuas acidity yog ib qho cuab yeej siv thiab cov cuab yeej siv, feem ntau yog siv los ntsuas pH tus nqi ntawm cov kua nruab nrab, ua ke nrog cov ion xaiv electrode kuj tuaj yeem ntsuas MV tus nqi ntawm ion electrode muaj peev xwm, dav siv hauv kev lag luam, kev ua liaj ua teb, kev tshawb fawb tshawb fawb, kev tiv thaiv ib puag ncig thiab lwm yam. Lub pH meter yog ib qho cuab yeej rau ntsuas pH ntawm cov tshuaj. Lub cev ntawm pH meter yog qhov tseeb potentiometer. Thaum ntsuas, ntxig cov hluav taws xob sib xyaw rau hauv cov tshuaj uas yuav tsum tau kuaj, thiab cov hluav taws xob sib txawv yuav raug tsim tawm vim qhov sib txawv acidity (hydrogen ion concentration) ntawm cov tshuaj yuav tsum tau kuaj, uas yuav tsum tau amplified los ntawm DC amplifier, thiab thaum kawg lub nyeem ntawv qhia (voltmeter) yuav taw qhia qhov ntsuas pH tus nqi. Lub ntsuas pH tuaj yeem siv nyob rau hauv thaj tsam ntawm 0-14pH.
Muaj ntau hom acidity meters, xws li desktop, portable, thiab gauge, thiab muaj ob hom kev nyeem ntawv qhia: digital thiab pointer.
PH meter yog ib qho cuab yeej siv thiab khoom siv, feem ntau yog siv los ntsuas pH tus nqi ntawm cov kua nruab nrab. Nws tseem tuaj yeem ntsuas qhov MV tus nqi ntawm ion electrode muaj peev xwm nrog cov ion xaiv electrode. Nws yog dav siv hauv kev lag luam, kev ua liaj ua teb, kev tshawb fawb tshawb fawb, kev tiv thaiv ib puag ncig thiab lwm yam.
Classification ntawm pH meter:
Raws li kev xav tau ntawm kev tsim khoom thiab lub neej, tib neeg tau tshawb fawb thiab tsim ntau hom pH ntsuas: Raws li qhov ntsuas qhov tseeb, nws tuaj yeem muab faib ua {{0}}.2 qib, 0 .1 qib, 0.01 qib lossis siab dua precision.
Raws li qhov loj ntawm lub ntsuas, muaj hom cwj mem (hom mini), hom portable, hom duab, thiab hom online rau kev soj ntsuam tas li thiab ntsuas. Raws li cov kev xav tau ntawm kev siv: cwj mem-hom (me me) thiab portable PH pH meters feem ntau yog siv los ntawm cov neeg soj ntsuam coj lawv mus rau qhov chaw kuaj xyuas. Qhov tseeb theem ntawm pH meter yog xaiv raws li qhov tseeb ntawm tus neeg siv rau kev ntsuas.
