1. Siv lub computer tswj system, tshwj xeeb software English Windows interface, nas, keyboard, man-machine dialogue, yooj yim to taub.

2. tuaj yeem pom tam sim no muaj peev xwm nkhaus (EV), thawj derivative nkhaus (dE / dV) thiab electrode muaj peev xwm (E), titration ntim (V), cov txiaj ntsig titration, thiab lwm yam.

3. Cov cuab yeej los ntawm potentiometric titration txiav txim siab qhov kawg ntawm titration thiab txiav cov txiaj ntsig tau.

4. Kev nco ua ntej titration, preset kawg taw tes titration, titration dawb paug thiab phau ntawv titration thiab lwm yam qauv, kuj tuaj yeem tsim lawv tus kheej cov kev sim siab hom raws li tus neeg siv yuav tsum tau ua kom tau raws li qhov kev sim sib txawv.

5. Titration system siv cov khoom siv corrosion-resistant, tuaj yeem ua ntau yam tshuaj tiv thaiv titration. Kev xaiv cov electrode sib txawv tuaj yeem ua tau: acid-base titration, redox titration, nag lossis daus titration, titration thiab pH ntsuas ntau dua titration, thiab lwm yam uas tsis yog-aqueous titration.

6. Tsis siv neeg tu, tsis siv neeg rehydration, tsis siv neeg dosing nqi.
