Qhov sib txawv ntawm acid meter thiab ph meter
Acidity meter thiab ph meter ob leeg yog tib yam, yog ib hom high-precision muaj hauv internet tsis siv neeg nruam nrhiav kom tau acidity thiab alkalinity ntawm lub analytical ntsuas.
Acidity meter yog abbreviated li pH meter, uas muaj ob ntu: electrode thiab galvanometer, nws yog ib qho cuab yeej siv thiab khoom siv, uas muaj peb ntu: siv electrode, iav electrode thiab galvanometer. 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.
Acidity meter yog ib qho cuab yeej siv feem ntau thiab cov cuab yeej siv, tseem hu ua PH meter. Nws yog tsuas yog siv los ntsuas cov acidity thiab alkalinity tus nqi ntawm cov kua nruab nrab, nrog rau qhov sib xws ion selective electrode kuj tseem ntsuas cov ion electrode muaj peev xwm MV tus nqi, BPH-200A series PH meter yog dav siv hauv kev lag luam, kev ua liaj ua teb, kev tshawb fawb. kev tshawb fawb, kev tiv thaiv ib puag ncig thiab lwm yam haujlwm. 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 ib qho cuab yeej rau kev 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 yog acidity ntawm cov tshuaj nyob rau hauv kev sim (hydrogen ion concentration) thiab tsim hluav taws xob sib txawv, nws yuav raug nthuav tawm los ntawm DC amplifier, thiab thaum kawg los ntawm qhov ntsuas ntsuas (voltmeter) taw qhia. tawm tias tus nqi pH ntawm cov tshuaj nyob rau hauv kev sim. Lub acidimeter tuaj yeem siv nyob rau hauv thaj tsam ntawm 0 txog 14 pH.
Kev ceev faj rau kev siv ph meter
1, Feem ntau, qhov ntsuas yuav tsum tau ntsuas ib zaug ib hnub thaum nws siv tas li; Feem ntau, qhov ntsuas tsis tas yuav tsum tau ntsuas dua hauv 24 teev.
2, kev siv cov electrode ua ntej rub tawm sab sauv kawg ntawm lub tes tsho roj hmab kom nws nthuav tawm qhov kawg ntawm lub qhov me me.
3, calibration ntawm cov tshuaj buffer feem ntau yog siv rau thawj zaug nrog pH=6 86 tov, lub thib ob lub sij hawm nrog ib tug tsis nyob ze rau pH tus nqi ntawm cov ntsuas, xws li cov ntsuas ntsuas yog acidic, qhov tsis yuav tsum tau xaiv pH=4.00; xws li cov tshuaj ntsuas yog alkaline, ces xaiv qhov tsis pH=9.18.
4, kev ntsuas, kev taw qhia ntawm cov hlau electrode yuav tsum nyob ruaj ruaj, txwv tsis pub nws yuav ua rau kev ntsuas tsis ruaj khov. 5, Tsis txhob tso cov electrode hauv dej distilled.
6, Khaws lub qhov muag hluav taws xob ntub dej, yog tias pom tias qhuav, nws yuav tsum tau tsau rau hauv 3mol / L potassium chloride tov los yog cov kua qaub me ntsis rau ob peb teev ua ntej siv los txo cov peev xwm ntawm cov electrode.
