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.
Features
- 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..
