Yuav ua li cas xaiv tus pH meter?
Thaum peb yuav ib lub pH meter, peb yuav tsum xub xav txog daim ntawv thov, xaiv tus cwj mem pH meter, portable pH meter, desktop pH meter los yog industrial pH meter; thib ob, xav txog qhov tseeb uas yuav tsum tau ntsuas, thiab xaiv qhov tseeb uas haum rau koj siv.
pH ntsuas tau siv dav hauv kev lag luam, hluav taws xob hluav taws xob, kev ua liaj ua teb, tshuaj, zaub mov, kev tshawb fawb thiab kev tiv thaiv ib puag ncig. 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.
Peb yuav tsum xav txog cov ntsiab lus hauv qab no thaum xaiv lub ntsuas acidity:
1. Raws li kev faib tawm ntawm daim ntawv thov, nws tuaj yeem muab faib ua: cwj mem hom pH meter, portable pH meter, kuaj pH meter thiab industrial pH meter, thiab lwm yam. Tus cwj mem hom pH meter yog siv los hloov cov kev ua haujlwm ntawm pH. xeem ntawv, thiab muaj 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.
Lub chaw kuaj pH meter yog lub desktop high-precision analytical ntsuas uas yuav tsum tau muaj kev ua haujlwm siab thiab ua haujlwm tag nrho, suav nrog kev 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, tsis yog 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 kev xav.
2. Kev faib tawm raws li qhov tseeb ntawm lub ntsuas pH: nws tuaj yeem muab faib ua 0.2, 0.1, 0.05, thiab 0.01. Tus lej tsawg dua, qhov tseeb dua.
3. Kev faib tawm raws li hom khoom siv: 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.
4. Raws li kev faib tawm ntawm 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.
5. Tshawb xyuas seb lub ntsuas pH puas muaj cov haujlwm ntxiv, piv txwv li, nws muaj tus qauv RS232 interface, thiab lwm qhov tseem ceeb yog seb qhov ntsuas kub puas yog tsis siv neeg lossis phau ntawv. Lub pH ntsuas nrog tsis siv neeg ntsuas kub yog qhov yooj yim dua li pH ntsuas nrog phau ntawv ntsuas kub. Koj tuaj yeem pom tus nqi ntawm ob.
