Mawonekedwe

1. Pogwiritsa ntchito makina oyendetsera makompyuta, mapulogalamu apadera a English Windows mawonekedwe, mbewa, kiyibodi, kukambirana kwa makina a munthu, kosavuta kumva.

2. Itha kuwonetsedwa nthawi yomweyo yokhotakhota (EV), curve yoyamba yotengera (dE / dV) ndi kuthekera kwa electrode (E), voliyumu ya titration (V), zotsatira za titration, ndi zina zambiri.

3. Chida ndi potentiometric titration zimangodziwiratu kumapeto kwa titration ndikuwerengera zotsatira zake.

4. Memory pre-titration, preset end point titration, blank titration ndi titration pamanja ndi zitsanzo zina, amathanso kupanga zoyeserera zawo zodzipatulira malinga ndi zofunikira za ogwiritsa ntchito kuti akwaniritse zofunikira zosiyanasiyana zoyeserera.

5. Titration dongosolo ntchito dzimbiri zosagwira zipangizo, akhoza zosiyanasiyana titration anachita. Kusankha ma elekitirodi osiyanasiyana kungakhale: acid-base titration, redox titration, mpweya titration, titration ndi pH muyeso zovuta kwambiri titration, ndi zina sanali amadzi titration.

6. Kuyeretsa zokha, kubwezeretsa madzi m'thupi, kufunikira kwa dosing.
