 Auto Kjeldahl Apparatus adopts international Kjeldahl method to add nitrogen to nitrogenous sample directly. Full intelligent software design can make experimenter finish the distillation of sample in minutes. It can automatically add quantitative required reagent and make intelligent inspections on various states. Distillation and condensation automatic cleaning system further improves measuring accuracy. Friendly interface of the instrument can display rich information, which makes users master its operation easily.



1. Manual/auto double-mode switch and automatically adding quantitative alkali liquor and boric acid absorbent solution

2. 10 experimental procedures can be stored to meet users' different requirements. Distillation time can be set at will. After distillation completion, it will give an alarm automatically.

3. Automatic cleaning system realizes intelligent pipeline cleaning function which make measuring accuracy higher.

4. Perfect safety protection system can measure and protect over-temperature and over pressure of distiller and pipeline.

5. Intelligent design of facilities around Kjedahl Apparatus contains safety protection design and non-existence prompt function.

6. Intelligent cooling water control system can control and inspect cooling water

7. Emergency stop operating function for emergency

8. Automatic inspection of failures and intelligent audible and visual alarm system
