Automatic Kjeldahl Nitrogen Analyzer Model: JK9830

Product Application:

The Kjeldahl method is a classic method for determining nitrogen. It is currently widely used for determining nitrogen-containing compounds in soil, food, animal husbandry, agricultural products, feed, and other applications. This method requires three steps: sample digestion, distillation separation, and titration analysis.

The JK9830 Automatic Kjeldahl Nitrogen Analyzer is an analytical system developed based on the classic Kjeldahl method. It automatically distills and separates samples and analyzes nitrogen (protein) using external techniques. Its methods and manufacturing procedures comply with the manufacturing standard "GB/T 33862-2017 Fully (Semi-) Automatic Kjeldahl Nitrogen Analyzer" and relevant international standards.

Product Features:

· The JK9830 Automatic Kjeldahl Nitrogen Analyzer features an embedded operating system with proprietary intellectual property rights and a 7-inch color touchscreen. Its menu uses Chinese characters for interactive dialogue, making it easy to learn and operate.

· Automatic shut-off function: The system automatically shuts down after 60 minutes of unattended operation, ensuring energy conservation, safety, and reliability.

· Operation instructions, reagent preparation, precautions, and maintenance information are displayed on the screen for easy access.

· A built-in protein coefficient lookup table allows users to access, query, and participate in system calculations.

· The JK9830 Automatic Kjeldahl Nitrogen Analyzer has 16MB of data storage, capable of storing 100,000 sample records.

· 99 user-defined program (recipe) management system.

· Multi-function interface connects to the refrigeration system and reagent tank level sensor.

· Time-delayed analysis allows for measurement of nitro-containing samples.

· Metal (304 stainless steel) steam boiler: Stable, reliable, and pressure-resistant.

· The steam system provides a constant pressure steam flow, ensuring stability and safety.

· Professional, high-performance pumps, valves, and imported piping ensure product reliability and stability.

Safety Protection Systems:

· Leakage protection system ensures operator safety.

· If the digestive tube is missing, the system will not add reagents or heat, preventing injuries from reagents or steam.

· If the safety door is not closed, the system will not operate. The 5mm thick transparent safety door ensures personal safety.

· If the steam system is dehydrated, the system will automatically shut down and alarm, preventing accidents.

· If the steam boiler is overheated, the system will automatically shut down and alarm.
