Qhov sib txawv thiab kev sib txuas ntawm pH meter, acidity meter thiab ion meter
PH meter yog ib qho cuab yeej siv thiab khoom siv, feem ntau yog siv los ntsuas pH tus nqi ntawm cov kua dej. Ib qho pH meter raug txuas nrog lub voltmeter los ntawm kev ntsuas tshwj xeeb (iav electrode) los ntsuas thiab tso saib pH nyeem. Siv dav 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 cov cuab yeej tshuaj xyuas tseem ceeb rau QS thiab HACCP ntawv pov thawj hauv cov chaw tsim khoom noj thiab cov dej haus.
Lub pH meter yog ib qho cuab yeej rau ntsuas pH ntawm kev daws. 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 Qhov taw qhia nyeem ntawv (voltmeter) yuav taw qhia qhov ntsuas hluav taws xob hluav taws xob. Lub pH ntawm cov tshuaj.
ion meter yog ib qho cuab yeej siv hluav taws xob siv los ntsuas qhov concentration ntawm ions hauv cov kua dej aqueous. Nws siv lub teeb xiav xiav thiab ob-kab digital cov kua siv lead ua kua, uas tuaj yeem tso saib pX tus nqi thiab tus nqi kub tib lub sijhawm. Nws yog tsim rau kev kuaj sampling thiab kev txiav txim siab ntawm ntau yam ion concentrations nyob rau hauv aqueous kev daws teeb meem nyob rau hauv cov tsev kawm ntawv, kev tshawb fawb institutes, ib puag ncig xyuas, industrial thiab mining lag luam thiab lwm yam departments.
qhov txawv
Acidity yog hais txog lub peev xwm ntawm tus qauv kom nruab nrab cov tshuaj alkaline, thiab tus nqi pH hais txog qhov tsis zoo logarithm ntawm hydrogen ion kev ua hauv cov qauv tshuaj.
Cov txheej txheem tseem ceeb ntawm pH meter ntsuas yog nyob rau hauv pH meter electrode. Txhawm rau ntsuas cov qauv sib txawv, nws yog ib qho tsim nyog yuav tau xaiv ib qho pH electrode haum.
Qhov yuam kev ntawm pH meter ntsuas los ntawm qhov yuam kev ntawm pH meter electrode, pH meter party, thiab pH tus qauv tsis
Tus nqi tso saib ntawm pH meter tom qab ntsuas kub yog qhov pH tus nqi ntawm qhov ntsuas kub ntawm cov qauv
Kev sau ntawv ntawm pH yuav tsum yog pH, tsis yog PH
