Qhov sib txawv thiab kev sib txuas ntawm PH Meter, Acid Meter thiab Ion Meter
PH meter, yog ib qho cuab yeej siv feem ntau, feem ntau yog siv rau kev ntsuas qhov tseeb ntawm acidity thiab alkalinity ntawm cov kua nruab nrab, ib qho pH meter los ntawm kev ntsuas tshwj xeeb [iav electrode (iav electrode)] txuas nrog lub voltmeter, ntsuas thiab tso saib cov pH nyeem ntawv. 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. Cov cuab yeej tseem yog lub Hoobkas khoom noj khoom haus, lub Hoobkas dej haus QS, HACCP ntawv pov thawj hauv cov khoom siv tshuaj xyuas tsim nyog.
Acidity meter yog cov cuab yeej los txiav txim siab pH tus nqi ntawm cov tshuaj. Lub cev tseem ceeb ntawm acidimeter yog qhov tseeb potentiometer. Kev txiav txim siab ntawm cov khoom siv hluav taws xob tso rau hauv cov tshuaj ntsuas, vim tias acidity ntawm cov tshuaj nyob rau hauv kev sim (hydrogen ion concentration) sib txawv thiab tsim hluav taws xob sib txawv, nws yuav raug nthuav tawm los ntawm DC amplifier, zui los ntawm qhov ntsuas ntsuas (voltmeter) taw qhia. tawm tias tus nqi pH ntawm cov tshuaj nyob rau hauv kev sim.
Ion Meter yog ib qho khoom siv hluav taws xob siv los ntsuas qhov concentration ntawm ions hauv cov kua dej aqueous, nws siv lub teeb xiav xiav, ob kab ntawm cov duab digital kua siv lead ua, tuaj yeem tso saib pX tus nqi thiab tus nqi kub tib lub sijhawm. Nws yog tsim rau cov tsev kawm qib siab thiab cov tsev kawm ntawv qib siab, cov koom haum tshawb fawb, kev soj ntsuam ib puag ncig, kev lag luam thiab kev lag luam mining thiab lwm lub tuam tsev ntawm lub chaw soj nstuam coj mus kuaj los txiav txim siab qhov concentration ntawm ntau yam ions hauv cov tshuaj aqueous.
Qhov txawv
Acidity yog hais txog lub peev xwm ntawm tus qauv los ua cov tshuaj tiv thaiv nruab nrab nrog cov tshuaj alkali, thiab PH tus nqi yog hais txog qhov tsis zoo logarithm ntawm kev ua ntawm hydrogen ions hauv cov qauv tshuaj.
Cov thev naus laus zis ntawm PH meter ntsuas yog nyob hauv PH meter electrode, ntsuas ntau hom qauv yuav tsum xaiv qhov tsim nyog PH electrode.
PH meter ntsuas yuam kev los ntawm PH meter electrode, PH meter party, PH standard buffer yuam kev.
Tus nqi tso saib ntawm PH meter tom qab them nyiaj kub yog PH tus nqi raws li qhov ntsuas kub ntawm cov qauv.
Kev sau ntawv ntawm pH yuav tsum yog pH, tsis yog PH.
