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.
