Dab tsi yog hom acidity meters - yuav ua li cas yog acidity ntsuas
Feem ntau, cov ntsuas acidity tuaj yeem raug cais raws li daim ntawv thov, ntsuas qhov tseeb, nyeem ntawv qhia, thiab hom khoom siv:
1. Kev faib tawm raws li qhov tseeb ntawm qhov ntsuas
Nws tuaj yeem muab faib ua {{0}}.2 qib, 0.1 qib, 0.02 qib, 0.01 qib thiab 0.001 qib, qhov me dua tus naj npawb, qhov siab dua qhov tseeb.
2. Muab faib raws li kev nyeem ntawv qhia
Nws tuaj yeem muab faib ua ob hom: hom pointer thiab digital zaub hom. Pointer pH metres tsis tshua 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 ntsuam titration.
3. 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 ntawm cov nti yog kim heev.
4. Kev faib tawm raws li daim ntawv thov
Nws tuaj yeem muab faib ua cwj mem hom PH meter, portable PH meter, kuaj duab PH meter thiab muaj PH meter, thiab lwm yam. Tus cwj mem hom pH meter yog tsuas yog siv los hloov cov kev ua ntawm pH xeem ntawv, thiab muaj cov yam ntxwv ntawm tsawg precision. thiab siv tau yooj yim. Portable pH meters yog tsuas yog siv nyob rau hauv qhov chaw thiab kev soj ntsuam txoj kev, yuav tsum tau siab precision thiab zoo meej zog. Lub chaw kuaj pH meter yog lub desktop high-precision analytical ntsuas uas yuav tsum tau muaj kev ua haujlwm siab thiab ua tiav tag nrho, qee qhov muaj xws li luam tawm, ua cov ntaub ntawv, thiab lwm yam. Industrial pH meters yog siv rau kev ntsuas tas li ntawm cov txheej txheem kev lag luam. Lawv 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, ntxuav, tiv thaiv kev cuam tshuam thiab lwm yam teeb meem.
