Main feature
- 5.7-inch touch screen display, Chinese interface, office operation, easy to understand;
- Modular design, consisting of volumetric titration (coulomb) device, control device, measuring device (potential, conductance, permanent stop), potentiometric titration, conductance titration, permanent stop titration can be achieved through different combinations;
- Support pre-titration, preset end point titration, blank titration, manual titration and other modes, or create your own special mode according to user experiment requirements to meet different experimental requirements;
- Different electrodes can be used: acid-base titration, redox titration, precipitation titration, complexometric titration, non-aqueous titration, etc.
- Support control panel control operation, which can display the titration curve and first derivative and map in real time, and edit and modify the titration mode;
- Support computer control operation, display potential curve and its first and second derivative maps on the computer. Equipped with WT-TT-5 titration software, it can operate various titration analysis in computer virtual interface, which can realize the editing, modification, titration curve and data storage, titration result calculation formula editing, database processing and statistics functions of titration method;
- The titration system uses materials resistant to perchloric acid corrosion and can perform a variety of titration reactions;
- The stirring system adopts PWM modulation technology, software speed regulation and low noise;
- Support RS232 connection PC, two-way communication, random donation special software; support connection (TP-16 type, TP-24 type or TP-40 type) serial printer, print measurement data and results.
