Product Description

Laboratory Automatic Kjeldahl Analysis for Analyzing Soil and Food

 Kjeldahl auto analyzer is an auto analyzer which with characters including auto reagent addition, auto distillation and separation of sample, auto collection of samples and auto termination of distillation; the separation methods which adopted is 100% corresponds to the National and International standards.



Feature
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
