Yuav siv li cas thiab daws cov teeb meem ntawm kev ntsuas pheter
Ceev faj ua ntej siv:
1) Thaum siv thawj zaug, vim qhov kev sojntsuam hluav taws xob tsis yooj yim, nws yuav cuam tshuam qhov ntsuas qhov tseeb ntawm qhov ntsuas. Yog li ntawd, soak lub electrode nyob rau hauv ib tug 3mol / l poov tshuaj tshuaj chloride tov rau 2 teev ua ntej.
2) Npaj ntawm 3Mol / L Cov poov tshuaj tshuaj dawb tshuaj: hnyav 223.65g ntawm poov tshuaj chloride thiab yaj nws nyob rau hauv ib litrilled lossis deistized dej. Dissolve reagent kiag li kom tau txais 3Mol / l poov tshuaj chloride tov.
3) Hloov cov electrode ib xyoos ib zaug (tsis hais txog seb lub electrode yog ua haujlwm lossis tsis yog).
Cov kauj ruam siv:
1, npaj
1. Txuas lub zog thiab luv luv nias lub "Tawm" khawm kom tig mus rau lub pha meter preheating.
2. Huv lub electrode nrog dej distilled tsawg kawg peb zaug.
3. Npaj cov kev ntsuas daws teeb meem thiab coj tus nqi tsim nyog rau hauv lub raj ntxuav huv.
2, ntsuas hluav taws xob (PHOT me me tsis xav tau calibre rau lub sijhawm ntev)
Tsis siv neeg calibration: fenserse ntawm electrode hauv qab qib ntawm cov qauv tsis daws. Luv Nias lub "Ntsuas" khawm thiab soj ntsuam sab saum toj sab laug ntawm lub ntsuas. Calibration xaus thaum tus ntawv pib tsis muaj flashes. Luv xovxwm 'Nyeem / Paub meej' khawm kom xaus
9. Puas yog K Meter electrode zaub zaub tsis hloov pauv hauv txhua qhov qauv?
Teb: vim hais tias cov electrodes tsis tau txuas nrog qhov ntsuas. Txoj kev ua yog thawj zaug kaw, thiab tom qab ntawd rov ua dua lub electrode thiab ntsuas. Vim tias electrode puas, nws yog qhov tsim nyog los hloov nws nrog lub tshiab nyob rau hauv lub sijhawm.
10. Puas yog qhov ntsuas tsis ruaj khov thiab siv sijhawm ntev?
Teb: Vim tias cov electrodes yog kev laus. Lub sijhawm teb ntawm cov electrode hauv cov kev daws teeb meem tsis tuaj yeem kuaj. Yog tias nws yog qhov ntau dua 1 feeb, lub electrode xav kom qhib tau lossis hloov nrog lub tshiab electrode. Yog tias lub sijhawm teb ntawm kev ntsuas ntas luv yog luv tab sis cov qauv ntsuas tsis ruaj khov, nws qhia tias chav electrode tsis haum rau ntsuas cov qauv ntsuas. Thov xaiv cov hluav taws xob tsim nyog raws li cov lus qhia electrode.
11. Thaum cov qauv kub yog 10 degree, puas yog cov ntsuas tawm tus nqi pH ntawm 10 degree lossis 25 degree
