Name:  Automatic Kjeldahl nitrogen analyzer 
 
Model:  KDN-04C/KDN-08C/KDN-20C

 

Note: KDN Series Automatic Kjeldahl nitrogen analyzer, the digestive furnace is not included in standard configuration
 
Characteristics

1. Adopt microcomputer controlling process
2. Automatically control distills, add water, control water level, and cut off the water supply
3. Various security protections: digestive system security device, steam generator water shortage alarm, water level detection fault alarm
4. 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.
5. Once detected fault, the controlling system will power off automatically
6. Adopt tap water source, wide adaptability, and requirement for the test is low
