Product Description

Product Description

Introduction

Kjeldahl method is a classical method for the determination of nitrogen, which is now commonly used for the determination of soil, food, animal husbandry, agricultural products, feed and other nitrogenous compounds, and the determination of samples by this method requires three processes: sample digestion, distillation and separation, and titration and analysis. Three processes
JK9870 series automatic Kjeldahl nitrogen analyzer is based on the classical Kjeldahl nitrogen determination developed automatic distillation - titration technology, color method to determine the end point of the "nitrogen element" (protein) analysis system, the method, manufacturing in line with "GB/T 33862 Its method and manufacture conform to the manufacturing standard of "GB/T 33862-2017 Fully (semi-)automatic Kjeldahl nitrogen analyzer" and international relevant standards.

Reliable execution system:
- R, G, B color sensors are selected, with a wide range of color adaptability, high precision and fast response speed.
- Linear motor and syringe made in Germany, "plunger type titration pump", with high control precision and good stability.
"Metal material (304 stainless steel) steam kettle: stable, reliable performance, strong pressure resistance.

Safe protection system:
- Leakage protection system to prevent leakage of electricity, electric shock to protect the safety of the operator
- Digestion tube missing system does not add reagents, not heating, to prevent reagents, steam injury
- The safety door does not close the system does not work, 5mm thick transparent safety door to ensure personal safety.
- The system automatically stops and alarms when the steam system is short of water to prevent accidents.
- Steam pot over-temperature system automatically stops and alarms.
- Steam overpressure system alarm shutdown to prevent accidents
- Sample over-temperature alarm prevents the sample temperature from rising and affecting the analyzed data.
- Safe Soda Addition Mode can reduce the strong reaction of soda addition process to prevent pipe burst phenomenon.

(Automatic Kjeldahl Nitrogen Determination Instrument Operation Interface)

- Embedded operating system with independent intellectual property rights using a 10-inch color touch screen, the menu for the Chinese characters man-machine dialogue mode, easy to operate, easy to learn
" Automatic shutdown function, the system 60 minutes unmanned automatic shutdown, energy saving, safety, peace of mind
- Operating methods, reagent preparation, precautions, maintenance and maintenance placed on the screen to facilitate user inquiries, use
- R, G, B three titration curves can observe the titration process sample changes, to provide assistance for the analysis process
- Titration accuracy verification ensures the accuracy of analytical data.
- Titration cups are mounted for easy observation of the titration process and cup cleaning.
" Built-in protein coefficient lookup table for easy access and participation in system calculations
" Sample weighing data can be uploaded and input automatically, which reduces the tedious work and input errors of manual input.
" 16M data storage capacity can store 100,000 pieces of sample data for user's reference, 5.7CM automatic paper-cutting thermal printer.
- 99 groups of user-defined program (recipe) management system
- Through the machine USB interface can be stored data export for users to save in the computer, editing, use
- Multi-function interface can be connected to the refrigeration system, reagent bucket level sensor

Features

" Automatic Kjeldahl Nitrogen Determination without tap water is equipped with high efficient cooling water circulation system controlled by the main unit of the nitrogen detector, which is energy-saving, environmentally friendly and stable.
" Titrant concentration internal standard eliminates the systematic error of the difference between human and instrument judgment, high precision and convenience.
" Automatic shutdown function, the system is automatically shut down after 60 minutes of unmanned operation, energy saving, safety, peace of mind
" Sample weighing data is automatically uploaded, input, reduce manual input one by one cumbersome work and input errors
- Distillation while titration mode distillation and titration at the same time, when the titration reaches the end of the distillation at the same time to save analysis time
- Automatic discharge of digestion waste liquid to reduce the labor intensity of the staff
- Steam flow rate from 50% to 100% can be adjusted arbitrarily to suit different concentrations of samples.
" Steam system provides constant pressure steam flow, good stability and safety
" Shutdown automatic cleaning of the alkali pipeline to prevent clogging of the alkali pipeline, to ensure the accuracy of liquid supply
- Cooling water flow monitoring prevents sample loss due to insufficient cooling water flow, which can affect the analytical results.
" Nitro samples can be measured by delayed analysis.
