Product Description


The instrument is exclusively applied for determining protein or nitrogencontaining compound in nature. It is widely used in measuring protein contained in food, dairy products, livestock, meat products, agricultural products, beverage, beer, medicine, heath care products and fodder, agricultural testing soil formulated fertilization, environmental protection, center for disease control, R&D institution and universities and colleges, as well as and nitrogencontaining compound analysis in chemical industry and chemical fertilizer…

II.Feature description 

1. Reagent transport modeabandon the inflatable liquid feed method commonly adopted by domestic manufacturers, select Germany anticorrosive metering pump with original packaging (the same element supplier with foreign first class Kjedahl apparatus manufacturer) for liquid feeding, which is reliable and accurate performance. During using the pump, you can select vessel of any dimension and no need of sealing, and can put large volume liquid barrel away from operation table, which greatly improves working environment.

2.  Pipe lines and fittings---select American pipe lines and fittings, no gas or liquid leakage, and long service life.

3.  Front shell of instrument---stainless steel plate, beautiful, corrosion resistant, and easy to clean

4.Mainboard systemdesigned and manufactured by professional automation control company, great system stability, high precision and low fault rate.

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 protectionthe 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 alkalifyingthe alkalifying process is not once and instant but at interval, properly reducing acid or alkali overreaction.

IV.Operating System:

1.  The menu is Chinese-English man-machine interaction mode, easy to operate and learn

2.  Liquid (Reagent) input and display mode is ml; inout value is actual adding value, accurate, reliable and convenient.
