KDN-816 Nitrogen analyzer Introduction
According to the classical Kjeldahl principle. Safe, rapid, accurate, low cost,humanization. Automatic monitoring and fault alarm, allows you to more easily,more safety. Features
1.Use of international standards of the Kjeldahl method: concentrated sulfuric acid digestion, alkali distillation, boric acid, receiving, indicator titration;
2.Working mode: manual and automatic integrated, can bearbitrary switching;
3.Automatic mode: water, alkali, boric acid, distillation, cleaning, waste discharging, automatically; (excluding titration)
4.Manual mode: each step can be manipulated independently, separately, but also can be carried out at the same time;
5.Lye, boric acid receiving liquid automatic quantitative filling;
6.Distillation end automatic stop and alarm;
7.Emergency stop function, in case of emergency;
8.Display: 7 inch widescreen display fine color;
