ਫੀਚਰ

1. Using computer control system, special software English Windows interface, mouse, keyboard, man-machine dialogue, easy to understand.

2. Can be instantly displayed potential curve (EV), the first derivative curve (dE / dV) and electrode potential (E), titration volume (V), the titration results, etc.

3. Instrument by potentiometric titration automatically determine the titration end point and automatically calculate the results.

4. Memory pre-titration, preset end point titration, blank titration and manual titration and other models, can also create their own experiments dedicated mode according to user requirements to meet different experimental requirements.

5. Titration system using corrosion-resistant materials, can be a variety titration reaction. Selection of different electrode can be: acid-base titration, redox titration, precipitation titration, titration and pH measurement more complex titration, and other non-aqueous titration.

6. Automatic cleaning, automatic rehydration, automatic dosing value.
