    price: 5000.00 Dollar US$

    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.
