Product Introduction


  • This Kjeldahl analyzer is designed by a professional team with years of R&D experience of high-level Kjeldahl analyzer, and is with the advantages of science, simplicity, high stability and super-high cost performance.

  •  Distillation of the sample can be finished by two buttons, which makes the analyzer is easy for operation.



Product Function:


  • The amount of alkaline liquor is controlled by button and added quantitatively.

  • Distillation is controlled by button.

  • Steam flow, liquid level of the steam generator, and the circulating cooling water are all controlled automatically. 

  • Reagent adding to the sample and distillation could be handled by two buttons.

  • Water saving design: It is guaranteed that the circulating water flow-limiting valve open only during the distillation, water-saving and free from worry. automatically control circulating water flow,free from manual operation.

  • The panel is with the material of ABS engineering plastic, which is waterproof, electricity-proof and corrosion-proof.
