Main technical characteristics
1. Adopt the principle of potential titration method, configure the desktop computer, use the Windows operating platform and Chinese software interface, mouse, keyboard operation, man-machine dialogue.
2, the use of micro-computer automatic measurement, automatic printing, the test process to achieve microcomputer automation, intuitive and simple operation.
3, the selection of imported titration unit, stable and reliable performance, high measurement accuracy, very low transmission noise, good stability.
4. Multi-parameter setting and correction make the analysis of different kinds of samples simple, fast, shorter analysis time and the results more accurate.
5. Automatic judgment of end point and automatic filtration of false end point; without indicator, it is suitable for acid value analysis of various light and dark oil in petrochemical products, titration results and data storage, and can provide complete titration data for analysis and research.
6. Double-high resistance input, three-electrode system, the electrode potential is more stable and reliable; titration results and data storage.
7. If there are few test samples, only (0.1~5) g for each time, the test time is fast, and the test time of each test sample is about 5 minutes.
8. Display the test process curve and test results in real time. Can realize the test curve of printing, test results and test data (printer is the purchase).
9, automatic rehydration, automatic fixed value of adding fluid.
