Ntau qhov kev nkag siab zoo uas yuav tsum tau paub thaum yuav lub ntsuas ph meter thiab PH acidity meter
⑴ Kev faib tawm raws li daim ntawv thov: tuaj yeem muab faib ua cwj mem hom PH meter, portable PH meter, kuaj PH meter thiab industrial PH meter, thiab lwm yam. cov yam ntxwv ntawm tsawg precision thiab yooj yim siv. Portable pH meters yog tsuas yog siv rau ntawm qhov chaw thiab qhov chaw ntsuas, yuav tsum tau siab precision thiab zoo meej zog.
⑵ Kev faib tawm raws li qhov tseeb ntawm qhov ntsuas: nws tuaj yeem muab faib ua {{0}}.2, 0.1, 0.02, 0.01 thiab 0.001 ib. Tus lej tsawg dua, qhov tseeb dua.
⑶ Kev faib tawm raws li kev nyeem ntawv qhia: nws tuaj yeem muab faib ua ob hom: hom pointer thiab digital zaub hom. Pointer pH meters tsis tshua muaj siv tam sim no, tab sis cov ntsuas ntsuas ntsuas tuaj yeem tso saib cov txheej txheem hloov pauv tas li ntawm cov ntaub ntawv, yog li lawv tseem siv hauv kev tshuaj xyuas titration.
(4) Kev faib tawm raws li hom khoom: nws tuaj yeem muab faib ua hom transistor, integrated circuit type thiab single-chip microcomputer type. Tam sim no ntau microcomputer chips tau siv, uas txo qhov loj ntawm qhov ntsuas thiab tus nqi ntawm ib lub tshuab; tab sis tus nqi tsim tawm ntawm cov nti yog kim heev. Laboratory pH meter: Laboratory pH meter yog lub desktop high-precision analytical instrument uas yuav tsum tau muaj kev ua haujlwm siab thiab ua tiav tag nrho, suav nrog kev luam tawm, cov ntaub ntawv ua, thiab lwm yam. Muaj pH meter: Industrial pH meter yog siv rau kev ntsuas kev lag luam tas mus li. Nws tsis tsuas yog muaj kev ntsuas kev ua haujlwm, tab sis kuj muaj lub tswb thiab tswj kev ua haujlwm, nrog rau kev teeb tsa, tu, tiv thaiv kev cuam tshuam thiab lwm yam teeb meem.
Feature ntawm pH Meter
Cov iav ntawm pH electrode yuav maj mam muaj hnub nyoog dhau lub sijhawm, qhov gradient (tus nqi hloov pauv ntawm cov khoom siv hluav taws xob muaj peev xwm tshwm sim los ntawm kev hloov pauv ntawm chav tsev pH tus nqi) yuav deteriorate, thiab nws yuav siv sij hawm ntev kom ncav cuag lub peev xwm ruaj khov. Kev pabcuam lub neej ntawm cov electrodes dav dav tuaj yeem ncav cuag ob xyoos. Tsis tas li ntawd, qhov kub thiab txias kuj muaj txiaj ntsig zoo rau kev laus. Qhov kev laus ntawm kev khaws cia ntawm 100 degree rau ob peb lub lis piam yog sib npaug rau qhov kev laus ntawm kev khaws cia ntawm chav tsev kub rau ib xyoos.
Lub pH meter muaj qhov zoo ntawm kev ntsuas qhov tseeb, kev ntseeg siab, thiab yooj yim installation thiab txij nkawm. Nws kuj tseem ceeb rau kev ua qias tuaj thiab yuav tsum tau calibration nquag. Feem ntau, nws yog calibrated txhua ib mus rau ib thiab ib nrab lub hlis, thiab cov electrode yog hloov txhua ob xyoos.
