Product Details

Kjeldahl method is a classic method for nitrogen determination. At present, the Kjeldahl method is commonly used for the determination of soil, food, animal husbandry, agricultural products, feed and other nitrogen-containing compounds. Separation - three processes of titration analysis.
The CJK9830/9830A automatic Kjeldahl nitrogen analyzer is an analysis system developed based on the classic Kjeldahl method for automatic distillation, automatic separation and analysis of "nitrogen" (protein) through external related technologies. Its methods and manufacturing conform to relevant international standards.

Advantages
Intelligent operation. Safe Energy efficient.Three levels of rights management.
Intuitive operating system: Colorful touch screen, Chinese and English conversion.
Versatile range of applications: Measurement of nitrogen and protein content.
High-quality manufacturing materials: Steam and cooling system are made of 304 stainless steel.

Characteristics

The operating system adopts a 7-inch(10-inch for CJK-9830A) color touch screen, and the man-machine dialogue is simple and easy to operate and learn. The system automatically shuts down after 60 minutes of unattended operation, saving energy, safety, and peace of mind.

The three-level user management meets the relevant certification requirements, and the operation traceability query system. The titration volume input automatically calculates the analysis results and stores, displays, inquires, and prints, and has some functions of the fully automatic product.

Operation method, reagent preparation, precautions, maintenance screen query to facilitate users' daily application. The instrument has a built-in protein coefficient query table for users to access, query and participate in system calculation when analyzing proteins.

16M data storage capacity can store 100,000 sample data for users to consult, PID-regulated steam system can provide stable steam flow to ensure effective sample separation. Measurement of "nitro"-like samples by time-lapse analysis. 99 groups of user-defined programs (recipes) management system

The multi-function interface can be connected to the refrigeration system and the liquid level sensor of the reagent tank. Metal material (304 stainless steel) steam boiler has stable performance, reliability and strong pressure resistance.

Professional, high-quality pumps, valves, and imported pipelines fully guarantee product reliability and stability. Leakage protection system ensures operator safety. Absence of digestive tract protection system to prevent reagents and steam from hurting people.

5mm thick transparent safety door and safety door alarm system to ensure personal safety. Steam system water shortage alarm prompt, shutdown to prevent accidents. Steam boiler over-temperature alarm, shutdown to prevent accidents.

Safe alkali addition mode can reduce the strong reaction of alkali addition process and prevent pipe bursting phenomenon.

Sample over-temperature alarm and shutdown to prevent sample temperature rise and affect analysis data.(CJK9830A)

Steam overpressure alarm and shutdown to prevent accidents.(CJK9830A). Automatic discharge of digestive waste liquid reduces labor intensity of staff.(CJK9830A). 5.7CM automatic paper cutting thermal printer.(CJK9830A)

Shut down and automatically clean the alkali pipeline to prevent the alkali pipeline from being blocked and ensure the accuracy of liquid supply.(CJK9830A)

Steam flow 50%--100% can be adjusted arbitrarily for different concentration samples.(CJK9830A). Cooling water flow monitoring prevents insufficient water flow causing sample loss and affecting analysis results.(CJK9830A)
