Automatic Acid And Base Tester Of Petroleum Products - China

FDR-2271 Automatic acid and base tester of petroleum products

Scope

Compliance with SH / T 0251 "Determination of base number of petroleum products (perchloric acid potentiometric titration)" and GB / T 7304 "Petroleum products and lubricants and values assay (potentiometric titration)" standard experimental requirements

Features

1 - Computer control system, special software Chinese window interface, mouse, keyboard operation, man-machine dialogue, easy to understand.

2 - It can display the potential curve (E-V), the first derivative curve (dE / dV) and the electrode potential (E), the titration volume (V), the titration result and so on.

3 - The instrument uses the potentiometric titration method to automatically determine the end point of titration, and automatically calculate the results.

4 - The instrument has pre-titration, the default end titration, blank titration, manual titration and other modes, can also be based on user experiments to create their own dedicated mode to meet the different experimental requirements.

5 - Titration system using a corrosion-resistant materials, can be a variety of titration reaction.

Selection of different electrodes can be carried out: acid-base titration, redox titration, precipitation titration, complex titration, non-aqueous titration and other titration and pH measurement.

6 - Automatic cleaning, automatic rehydration, automatic value plus liquid.
