Reliable Automatic Kjeldahl Nitrogen Analyzer with Cooling Water Control System
NB9870 Laboratory protein content analysis Full Automatic Kjeldahl Nitrogen Analyzer
Applications:
The 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 NB9870 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. 33862-2017 "Full (semi) automatic Kjeldahl nitrogen analyzer" manufacturing standard and relevant international standards.
Features:
· Embedded operating system, 7-inch color touch screen
« Automatic shutdown function, the system automatically shuts down after 60 minutes of unattended operation, energy saving, safety, and peace of mind
· Operation methods, reagent preparation, precautions, and maintenance are placed on the screen for users to query and use
· Use R, G, B three-color color sensor, wide color adaptability, high precision and fast response speed
· 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
Validation of titration accuracy ensures the accuracy of analytical data
· The titration cup is clearly mounted to facilitate users to observe the titration process and clean the titration cup
« The instrument built-in protein coefficient query table for users to access, query and participate in the calculation of the system, which is convenient for users to use
« 16M data storage capacity can store 100,000 sample data for reference, 5.7CM automatic paper cutting thermal printer
· 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
« Measurement of "nitro"-like samples by time-lapse analysis
« Metal material (304 stainless steel) steam boiler: stable performance, reliable, strong pressure resistance
« The steam system provides constant pressure steam flow, stable and safe
· Professional, high-performance pumps, valves, and imported piping systems fully guarantee the reliability and stability of products
Safe protection system:
· The leakage protection system prevents leakage and electric shock to ensure the safety of operators
· Absence of digestive tract system does not add reagents or heat to prevent reagents and steam from hurting people
· The system does not work if the safety door is not closed, and the 5mm thick transparent safety door ensures personal safety
· The water shortage system of the steam system automatically shuts down and alarms to prevent accidents.
· The steam boiler over-temperature system automatically shuts down and alarms
