Laboratory Instrument Manufacturers - Automatic Kjeldahl Nitrogen analyzer – NANBEI
Laboratory Instrument Manufacturers - Automatic Kjeldahl Nitrogen analyzer – NANBEI Detail:
Characteristics
1. Using microcomputer to control the process
2. Automatically control the distillation, add water, control the water level, and cut off the water supply
3. Multiple safety protections: digestive system safety device, steam generator water shortage alarm, water level detection fault alarm
4. The instrument shell is made of special plastic-sprayed steel; the working area is made of ABS anti-corrosion board. Avoid chemical reagent corrosion and mechanical surface damage, acid 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.
