Product Description
Automatic Kjeldahl Analyzer Apparatus for Nitrogen Protein Analysis
NK9830 Auto Kjedahl Apparatus adopts international Kjedahl 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.
Performance Characteristics
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

Safety guarantee system
1.Electric leakage protection----protect personal safety of operators
2.Digestion tube absence protection----ensure system not working under the situation of digestion tube uninstalled.
3.Safety door protection----ensure safety of operators during distillation
4.Steam system overpressure protection----avoid danger caused by too high pressure in steam system
5.Distillation system water shortage protectionthe system will stop working if no water in distillatory kettle or too low water level
6. Prewatering mode- firstly add a certain amount of water to dilute the concentrated sulfuric acid in digestion tube before adding alkali, properly reducing sharp reaction of acid and alkali.
7,Alternate alkalifyingthe alkalifying process is not once and instant but at interval, properly reducing acid or alkali overreaction.
