Product Details
Automatic kjeldahl nitrogen analyzer:
1.The method is a classical method for determining nitrogen. At present, Kjeldahl method is widely used to determine soil, food, animal husbandry, agricultural products, feed and other nitrogen compounds. 

2.When using this method to determine samples, three processes are required: sample digestion - distillation separation - titration analysis.

3.It is an analytical system developed based on the classical Kjeldahl nitrogen determination method for the automatic distillation and separation of samples and the analysis of "nitrogen element" (protein) through external related technologies.

4. Its method and manufacturing comply with the manufacturing standards of GB/T 33862-2017 Full (Semi) Automatic Kjeldahl Nitrogen Determination Instrument and relevant international standards

Secure protection system
1.Leakage protection system to prevent leakage and electric shock to ensure the safety of operators

2.Digestive tube vacancy system does not add reagent or heat to prevent reagent and steam from injuring people

3.The system does not work when the safety door is not closed, and the 5mm thick transparent safety door ensures personal safety

4.Automatic shutdown and alarm of water shortage system of steam system to prevent accidents

5.Automatic shutdown and alarm of steam boiler over temperature system
The embedded operating system of JK9830 automatic Kjeldahl nitrogen determination instrument with independent intellectual property rights adopts a 7-inch color touch screen, and the menu is Chinese man-machine dialogue, which is easy to operate and learn.
Automatic shutdown function, the system automatically shuts down after 60 minutes of unmanned operation, saving energy, safety and confidence.
The operation method, reagent preparation, precautions, maintenance and maintenance are placed on the screen for users to query and use.
Professional and excellent pumps, valves and imported pipeline systems fully guarantee the reliability and stability of products..
The steam system provides constant pressure steam flow with good stability and safety.
Multi functional interface can be used to connect the refrigeration system and reagent tank level sensor.
Metal (304 stainless steel) steam cooker: stable, reliable and strong compression resistance.
