Kjeldahl protein analyzer

Automatic Kjeldahl Nitrogen Analyzer

III.  Safety guarantee system:

1. Electric leakage protection----protect personal safety of operators

2. Digestion tube absence protection----ensure system not working under the situation of digestion tube uninstalled.

3.  Safety door protection----ensure safety of operators during distillation

4.  Steam system overpressure protection----avoid danger caused by too high pressure in steam system

5.  Distillation system water shortage protection---the system will stop working if no water in distillatory kettle or too low water level

6. Prewatering mode-- firstly add a certain amount of water to dilute the concentrated sulfuric acid in digestion tube before adding alkali, properly reducing sharp reaction of acid and alkali.

7. Alternate alkalifying—the alkalifying process is not once and instant but at interval, properly reducing acid or alkali overreaction.
