The working principle of JK9870A auto Kjeldahl analyzer is based on the classical methods, it's namely the "color method" developed auto Kjeldahl analysis system. It is consistent with national and international standards and methods of Kjeldahl nitrogen. JK9870A is a high cost-performance instrument, all of its technical indexes have reached and / or even better than most of oversea similar products. Adoption of lot of patented technologies and components, making its performance overall better than the similar products on present market.

Advantages & Characteristics

Ø Addition of reagents, distillation, titration, analysis and calculation, record (data) storage, waste discharge and titration cup cleaning, all the above-mentioned program can be accomplished by simply click on ONE BUTTON.

Ø Display. 10-inch color touch screen, bilingual operating system (English & Chinese), interactive mode of operation.

Ø Titration curve display. Real-time observation, analysis to the titration process to see whether it's successful or fail and figure out the reason through curve. It's also able to analyze and determine whether the choice of titration is correct through the curve.

Ø High-integrated modular structure. Patented technology of "modular construction" is composed of steam section, titration section, control section, and crate section; therefore, the structure ensures reliable operation and easy maintenance.

Ø Titration cup exposed structure. It's convenient for users to observe and take out cup for cleaning.

Ø The system adopts the CPC company (US) fast for fluid pipe, to ensure that the system not leakage and prolong the life of equipment. The unique color label and color ring system which is able to help user avoid twisting and wrong operation.

Ø Fertilizer (nitro) analysis mode. Addition of fertilizer analysis capability achieves multi-purpose instrument which may save considerable cost for user.

Ø Multi-alkali adding technology. In the operation process, multi-alkali adding technology solves the problem of halfway quit in the analysis process which is due to shortage of alkali adding.

Ø The titrant concentrations autonomous calibration. This patented technology has solved the problem of titrant concentration calibration error by manual calibration, thus the result of analysis is more reliable.

Ø Steam flow adjustment. Steam flow output can be adjusted in accordance with user's needs. This innovation has solved the intractable headache on high concentration sample analysis..

Ø Recipe management system. To provide users with 10 sorts of different analytical formulas which are independent programming can be adopted at any time.

Ø Intelligent cooling system interface. After being connected with the "Intelligent Refrigeration Cycler" which Elite standing behind, "system-wide auto control" can be achieved completely and without having extra water source.

Ø Wireless mouse. Reduce operation intensity.

Safety Protection System

Ø Overtemperature protection system. It's composed of temperature sensor, CPU, overtemperature and overpressure protection system which is able to effectively prevent overtemperature and / or overpressure phenomena due to system failure to ensure a worry-free working condition for user.

Ø Distillation System water shortage alarm function. When the water level is too low or dry, the distillation pot may stop working and alarm systems, which is able to prevent the harm caused by water shortage or dryness effectively.

Ø Absence of protection of the digestive tube. When the digestive tube is not put in place, the system does not run, without alkali, distillation, wounding prevent wounding by reagent and / or contamination.
