Product Description

                          Fully automatic Kjeldahl nitrogen analyzer




Brief intoduction:

     The Kjeldahl method is a classic method for determining nitrogen. At present, the Kjeldahl method is generally used for the determination of soil, food, animal husbandry, agricultural products, feed and other nitrogen-containing compounds. When this method is used to determine samples, sample digestion-distillation Separation- titration analysis three process need to be p-proceeded.

     JK9870 automatic Kjeldahl nitrogen analyzer is an automatic nitrogen distillation-titration technology, color method to determine the end point "nitrogen element" (protein) analysis system developed based on the classic Kjeldahl nitrogen determination method.

Features:

 

1. The embedded operating system adopts a 7-inch color touch screen, and the menu is man-machine dialogue, which is easy to operate and easy to learn
2. Automatic shutdown function, the system automatically shuts down after 60 minutes of unmanned operation, which is energy saving and safe
3. Operation method, reagent preparation, precautions, maintenance are placed on the screen to facilitate user query and use
4. Use R, G, B three-color color sensor, wide color adaptation range, high precision, fast response speed
5. R, G, B three titration curves can observe the sample changes in the titration process, and provide help for the analysis process
6. Titration accuracy verification can ensure the accuracy of analysis data
7. The titration cup is installed conveniently for users to observe the titration process and clean the titration cup
8. The "plunger titration pump", composed of a linear motor made in Germany and an injection needle tube, has high control accuracy and good stability
9. The instrument has a built-in protein coefficient table for users to read, query and participate in system calculations for user convenience
10. 10. 16M data storage capacity can store 100,000 pieces of sample data for review, 5.7CM automatic paper cutting thermal printer
11.   99 groups of user-set program (recipe) management system
12.  Multi-function interface can be connected to refrigeration system, reagent tank level sensor
13.  Measurement of "nitro" samples through time-lapse analysis
14.  Metal material (304 stainless steel) steam boiler: stable performance, reliable, strong pressure resistance
15.  The steam system provides constant pressure steam flow, good stability and safety
16. Professional and excellent performance pumps and valves, and imported pipeline system fully guarantee the reliability and stability of the product
