Digital Kjeldahl Nitrogen Analyzer

Brand:NANBEI Model:KDN-04C 1. Using microcomputer to control the process 2. Automatically control distillation, water addition, water level control, and water cut supply 3. Various safety protections: digestive system safety devices, steam generators Water shortage alarm, water level detection fault alarm 4. The instrument shell is made of special sprayed steel; the work area is adopted ABS anti-corrosion board. Avoid chemical corrosion and mechanical surfaces Corrosion resistance, acid resistance and alkali resistance. 5. Once a fault is detected, the control system will automatically power off 6. Using tap water source, wide adaptability and low test requirements.
