Product Description

NB9870 fully Automatic Kjeldahl Nitrogen Analyzer

Application: It is widely used in food processing, feed production, tobacco, livestock, soil fertility, environmental monitoring, medicine, agriculture, scientific research, teaching, quality control and other fields for the test of nitrogen or protein content, can also be used for the test of ammonium, volatile fatty acid/alkali, and so on. The working principle of 9870 auto Kjeldahl analyzer is based on the classical methods, it's namely the "color method" developed auto Kjeldahl analysis system. Advantages & Characteristics: 1. Addition of reagents, distillation, titration, analysis and calculation, record (data) storage, waste discharge, all the above-mentioned program can be accomplished by simply click on ONE BUTTON. 2.Display. 7-inch color touch screen, bilingal operating system (English & Chinese), interactive mode of operation. 3. 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. 4. 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. 5. Titration cup exposed structure. It's convenient for users to observe and take out cup for cleaning. 6. Pre-warming function. The instrument itself is able to pre-heat automatically, and keep the certain temperature as preset, prior to use; therefore, it may save time and energy for user.

7. Fertilizer (nitro) analysis mode. Addition of fertilizer analysis capability achieves multi-purpose instrument which may save considerable cost for user. 8. 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. Safety Protection System: 1. Electric leakage protection. It can prevent the damage caused by the system leakage of user to the greatest extent to protect the user's personal body safety. 2. 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. 3. Steam pot. Selection of platinum carbon fiber plastic die-cast, long-term temperature 300℃ without distortion. It is currently the first product which adopts such materials in mainland China. 4. 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. 5.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.

Digestor,Waste gas collector,Neutralization unit are necessary equipment for kjeldahl analysis experiment. They need buy additional.
