Main feature
- LCD display, Chinese operation interface, can display relevant test parameters and measurement results;
- WT-TT-4A special software can be used to communicate with the computer, which can be displayed on the computer instantly; the titration mode can be edited and modified to realize remote operation and statistics of various statistical results;
- Support pre-titration, preset end point titration, blank titration, mode titration or manual titration, and can generate special titration mode according to user habits;
- Different electrodes can be used: acid-base titration, redox titration, precipitation titration, complexometric titration, non-aqueous titration, etc.
- 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;
- With power-off protection;
- Support RS-232 communication, external serial printer, print test data and results.
