Basic Nitrogen Analyzer(Potentiometric Titration)

Summary

This instrument is in accordance with the industry standard of the People's Republic of China SH / T0162-1992 (confirmed in 2006) "Determination method of basic nitrogen in petroleum products" and SH / T 0413-1992 (confirmed in 2005) "Minimal basic nitrogen content in liquid paraffin Designed and manufactured according to the requirements stipulated in the “Determination Method”, it is suitable for testing basic nitrogen content in petroleum products and trace basic nitrogen content in liquid paraffin.

I. Main technical features

1. Adopt the principle of potentiometric titration, configure a desktop computer, use the Windows operating platform, and the human-machine direct dialogue is simple and easy to understand.

2. It adopts microcomputer automatic measurement and automatic printing, and the test process realizes microcomputer automation, and the operation is intuitive and simple.

3. It adopts blue LCD large screen display, no logo button.

4. The key integral parts of the titration device are imported, with stable and reliable performance, high measurement accuracy, extremely low transmission noise and good stability.

5. Multi-parameter settings and corrections make analysis of different types of samples simple, fast, shorter analysis time, and more accurate results.

6. The endpoint is automatically judged, no indicator is needed, suitable for alkaline nitrogen analysis of a variety of light and dark oils in petrochemical products. The titration results and data are automatically stored and printed automatically, and a complete titration data spectrum can be provided for analysis and research.

7. Double high resistance input, electrode potential is more stable and reliable.

8. Automatic cleaning, automatic rehydration, fixed value replenishment; automatic filtering of false endpoints.

9. The test sample is small. According to the range of basic nitrogen content, only 1g ~ 50g is required. The test time is fast. The test time of each sample on the machine is about 5 minutes.
