Automatic Kjeldahl Nitrogen Analyzer + Automatic Lifting Curve Temperature Rising Digester

The F N series automatic Kjeldahl nitrogen analyzer adopts the industry-leading 16- bit three-primary color sensor, high-precision fuzzy search titration end point determination technology, combined with an advanced titration system structure to ensure more accurate titration. The unique alkali pump anti-crystallization technology completely eliminates the problem of alkali pump crystallization and improves instrument reliability. The modular structural design and multiple safety protections greatly ensure the stability, reliability and result accuracy of the product, as well as the safety of operators and the instrument. It features a humanized operation interface that is simple and easy to use; a complete experimental configuration system to meet various experimental requirements; a powerful self-learning function to facilitate users to establish their own experimental databases; the end point color user fine-tuning technology and end point color learning function can not only accurately adapt to various detection occasions, but also bring users a technological and humanized experience.
