Automated Kjeldahl Nitrogen Analyzer

自动凯氏氮分析仪

Busy food and feed labs with strict traceability needs can link dosing, digestion, distillation and titration in a single automated workflow. After digestion at up to 420 °C, each sample cycles in 4–8 min, giving 20–60 samples/h with RSD ≤ 1 percent. Protein factors from 5.7 to 6.38 are stored, so results report directly.
