TOP
This Automatic Kjeldahl Nitrogen Protein Analyzer is a measuring instrument designed based on the principle of Kjeldahl nitrogen determination. It is mainly used for the determination of sample nitrogen content and protein content. It adopts microcomputer automatic control, and the manual and automatic modes can be switched each other. It has functions such as automatic distillation control, automatic water addition, automatic water level control, and automatic water stop.
Characteristic:
Adopt microcomputer controlling process; include manual mode and automatic mode. Can be set and switched according to user's need.
Large array LCD display, touch key, easy to operate.
Automatically control distill, add water, control water level are cut off water supply.
Various security protections: digestive system security device, steam generator water shortage alarm, water level detection fault alarm.
Stored operation procedure quantity: 250
Instrument shell adopts specially made plastic spray steel. Working area adopts ABS anticorrosive board, avoid chemical reagent corrosion and mechanical surface damage, acid proof and alkali proof.
Once detected fault, controlling system will power off automatically.
