Alkaline nitrogen content analyzer

1Alkaline nitrogen content analyzerKey Features:

　2. The titration device is a Swiss imported exchange unit (Switzerland) with stable and reliable performance and low transmission noise.

3. The combination of automatic cleaning, automatic fluid replenishment, constant value liquid addition, and electromechanical organic technology.

4. Multi parameter setting and correction make the analysis of different types of samples simpler, faster, with shorter analysis time and more accurate results.

5. The endpoint is automatically determined without the need for an indicator. The titration results and data are automatically stored and printed, and complete titration data can be provided for analysis and research.

6. Double high impedance input ensures more stable and reliable electrode potential.
