1. Product introduction

JC-9870 automatic Kjeldahl nitrogen analyzer is a "nitrogen element" (protein) analysis system developed based on the classic Kjeldahl method of automatic distillation, titration technology and color method to determine the end point. , International standards.
This product has stable and reliable performance and is widely used in basic analysis, technology research and development, product quality control and other fields, and is an ideal substitute for imported products.

3. Product features

1) Operating system: 7-inch color touch screen is adopted, and the menu is Chinese character man-machine dialogue mode, which is easy to operate and easy to learn

2) The operation guide is screened: the daily operation, reagent preparation, maintenance, and maintenance work and rest are placed on the screen to facilitate users to query and use

3) Titration sensor: R, G, B three-color color sensor is selected, which has a wide range of color adaptation, high precision and fast response speed.

4) Titration curve: The three titration curves of R, G and B can observe the change of the sample during the titration process and provide help for the analysis process

5) Dosing pump: a "plunger titration pump" composed of a German-made linear motor and an injection needle, which has high control accuracy and good stability

6) Verification of titration volume: verify whether the accuracy of the titration system is reliable to ensure the accuracy of the analysis data

7) Titration cup: The surface mounted is convenient for users to observe the titration process and clean the titration cup

8) Protein coefficient query: The instrument has a built-in protein coefficient query table for users to read, query and participate in system calculation, which is convenient for users to use

9) Analysis data storage, query and printing: The data storage is up to 140,000 pieces of sample data for users to consult, and the printer is a 57CM automatic paper cutting thermal printer

10) One machine and two uses: In addition to measuring "amino" samples, this product can also measure "nitro" samples, such as "nitroammonium" fertilizers, which can save users 50% of purchase costs

11) Refrigeration circulator interface: "Refrigeration system" does not need to be turned on or off. When the nitrogen analyzer is heated, the "refrigeration system" automatically starts to cool down the nitrogen analyzer, and the "refrigeration system" automatically shuts down when the nitrogen analyzer is turned off.

12) Ammonia separator (splash-proof bottle): choose soda-lime tempered glass material that is resistant to strong alkali corrosion to completely solve the corrosion of the anti-ammonia separator caused by long-term soaking in strong alkali

13) Leakage protection system: prevent personal injury caused by leakage of the instrument and electric shock caused by various reasons, and protect the operator

14) Absence protection of digestive tube: When the digestive tube is not put into the system, the system does not add reagents or heat to prevent reagents and steam from hurting people

15) Safety door protection: The system does not work when the door is not closed, and the 5mm thick transparent safety door ensures personal safety

16) Metal material (304 stainless steel) steam cooker: stable performance, reliable, strong pressure resistance

17) Water shortage protection of steam system: When the steam system is short of water, the system will automatically shut down and alarm to prevent accidents.

18) Steam boiler over-temperature protection system: If the distillation system fails and the temperature in the steam boiler is too high, the system will automatically shut down and alarm

19) Safe alkali addition mode: This mode can reduce the strong neutralization reaction in the alkali addition process to prevent pipe bursting.
