NB-04 Kjeldahl Nitrogen Analyzer

NB-04 Kjeldahl Nitrogen Analyzer

Model:NB-04 Kjeldahl Nitrogen Analyzer
Application:Kjeldahl nitrogen analyzer widely used for protein content and nitrogenious compounds testing analysis in soil,feed,food,grain,milk,drink,water,medicine and chemical....

KDN-04C Kjeldahl Nitrogen Analyzer

1. Adopt microcomputer controlling process
2. Automatically control distills, add water, control water level and cut off 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, controlling system will power off automatically
6. Adopt tap water source, wide adaptability, and requirement for test is low.
