Cia thiab txij nkawm txoj kev ph meter (acidity meter) electrodes
Cov electrode ntawm ph meter (pH meter) yuav tsum tau muab khaws cia raws li hauv qab no:
Thov khaws cov electrode hauv 3mol/L potassium chloride tov (3 M KCl) thaum tsis siv; Nws tuaj yeem khaws cia hauv pH7.00 tsis nyob rau lub sijhawm luv. Lub neej kev pab cuam ntawm ph meter electrode yuav luv dua yog tias nws qhuav qhuav los yog tsau rau hauv dej distilled ntev.
Txoj kev tu ntawm ph meter (pH meter) electrode:
Tom qab siv cov electrode ntawm ph meter rau ib lub sij hawm, yog tias nws pom tias txoj kab nqes qis dua thiab cov lus teb ceev yuav qeeb, cov hauv qab no tuaj yeem sim.
1. Yog tias cov qauv ntsuas muaj cov protein, cov electrode membrane tuaj yeem ntxuav nrog pepsin/hydrochloric acid lotion (ME51340068).
2. Yog tias cov qauv ntsuas yog oily / organic kua, nws tuaj yeem ntxuav nrog acetone lossis ethanol.
3. Yog tias pom tias cov kua winding ib feem ntawm cov electrode ntawm ph meter ua qias neeg thiab dub, cov kua winding tuaj yeem raug ntxuav nrog mercaptan ntxuav kua (ME51340070).
4. Ua kom cov electrode membrane.
Txoj kev ua kom: tsau cov tshuaj electrode regeneration (ME51340073) ntawm ph meter rau 30 vib nas this, thiab tom qab ntawd tsau hauv 3mol / L KCl tov rau 5 teev.
Kev faib tawm ntawm PH meter thiab acidity meter
1. Raws li qhov ntsuas qhov tseeb, nws tuaj yeem muab faib ua 0 2- qib PH meter, 0.1- qib PH meter, acidity meter, {{5} }.
2. Raws li qhov ntim ntawm qhov ntsuas, muaj cwj mem PH meter, acidity meter (mini PH meter, acidity meter), portable PH meter, acid-base meter thiab desktop PH meter.
3. Muaj cov ntsuas PH hauv online thiab cov ntsuas acidity rau kev soj ntsuam thiab ntsuas hauv online.
4, raws li kev xav tau ntawm kev siv: cwj mem PH meter, acidity meter (mini PH meter) thiab portable PH meter, acidity meter feem ntau yog coj mus rau qhov chaw los ntawm cov neeg soj ntsuam kuaj.
5. Xaiv PH meter, thiab qhov tseeb ntawm acidity meter yog ntsuas los ntawm cov neeg siv.
