Product Description Product Description Automatic KjeldahI nitrogen analyzer ZDDN-II is a measuring instrument designed base on the principle of KjeldahI nitrogen determination. It is mainly used for the determination of sample nitrogen content and protein content. It adopts microcomputer automatic control, and the manual and automatic modes can be switched each other. It has functions such as automatic distillation control, automatic water addition, automatic water level control, and automatic water stop. Applicable to the analysis, teaching and research of grain and oil testing, feed analysis, plant nutrient testing, soil and fertilizer testing, environmental protection, medicine, chemical industry and other industries, mainly used to test grain, food, dairy products, beverages, feed, soil, water, medicine, ammonia nitrogen, protein nitrogen and other contents in sediments and chemicals. This instrument also is one of the necessary instruments for the detection of physical and chemical properties of soil Sanpu.Product Advantages1.The automatic KjeldahI nitrogen analyzer adopts microcomputer for process control, including manual mode and automatic mode, which can be set and switched according to your needs.★In automatic mode: The whole process of adding boric acid, adding alkali, distilling and absorbing ammonia can be completed automatically at one time. The volume of adding boric acid and alkali and the time of distillation and absorption can be set by yourself.★In manual mode: The three processes of boric acid addition, alkali addition and distillation absorption can be manually operated independently, and the volume and time can be controlled by themselves to meet the needs of professional users.2. Large-screen dot-matrix LCD display, touch buttons, easy and convenient operation.3. Automatic KjeldahI nitrogen analyzer with automatic distillation control, automatic water addition, automatic water level control, and automatic water cutoff.4. Various safety protections: digestive tube safety door device, steam generator water shortage alarm, water level detection failure alarm.5. The maximum number of stored operating programs is 250.6. The shell is made of special plastic-sprayed steel plate, and the working area is made of ABS anti-corrosion panel, which is resistant to chemical reagent corrosion and mechanical damage to the surface, and is resistant to acid and alkali.7. Water level detection, low water level alarm, instrument control system failure can automatically cut off the power.Detailed Photos Please note.The appearance and packaging of the product are continuously upgrading.Product ParametersAutomatic Kjeldahl azotometer determination varietiesGrain, feed, food, dairy products, beverages, soil, water, drugs, sediments and chemicals, etc.Working modeAutomatic (without titration)Water intake methodTap water and distilled water, which can be used in a wide range of areasSample amountSolid 0.20g~2.00g, semi-fixed 2.00g~5.00g, liquid 10.00ml~25.00mlMeasuring range0.1mgN~200mgN (mg nitrogen)Recovery rate≥99% (relative error, including digestion process)Distillation speed5~15 minutes/sample (depending on the amount of sample)Cooling water consumption3 L/minRepetition rateRelative standard deviationPower supplyAC220V/50HzPower1000WWater supplyWater temperature is less than 20oCDimensions430mm×360mm×670mmWeight25 KgNoted.The standard configuration does not include digestion furnace, and the digestion furnace is optional.The automatic KjeldahI nitrogen analyzer can choose the digital display digestion furnace with 4 holes, 8 holes, 12 holes and 20 holes to choose from. It takes about 60-90 minutes to digest a batch of samples (Depending on the nitrogen content). Harmful gases such as SO2 escaping from the digestion pipe are discharged from the water into the sewer through the collection pipe through the suction tee.Note: The ZDDN - II model can also choose manual mode.Agri-testing InstrumentFAQQ1.
