Product Details
Kjeldahl nitrogen determination
1. The principle is an automatic intelligent protein detection instrument, which is widely used to detect the total content of ammonia nitrogen and protein nitrogen in cereals, oils, foods, dairy products, beverages, feeds, soils, fertilizers, sediments and chemical products.

2.It is an important physical and chemical analyzer for product quality detection.
KDN series protein analyzer adopts microcomputer for process control.
Automatic distillation control, automatic water adding, automatic water level control and automatic water cut-off.
Various safety protections: digestive tube safety valve device, steam generator water shortage alarm, water level detection fault alarm.
The shell of the crude protein tester is made of special sprayed steel plate, and the working area is made of ABS anti-corrosion panel to prevent chemical reagent corrosion and mechanical damage to the surface, and it is acid and alkali resistant.
Water level detection, low water level alarm, instrument control system failure can automatically power off.
The instrument uses tap water, with wide adaptability and low requirements for experiments.
Protein tester can measure varieties: grain, feed, food, dairy products, beverage, soil, water, medicine, sediment and chemicals.
