Infitek Fully Automatic Kjeldahl Analyzer with Safety Door Protection
Features
- The control system adopts a 10 inch color touch screen to uniformly control the nitrogen analyzer host and refrigeration system, without the need for multiple switch settings, which is convenient, simple, and safe.
- The standard cooling system can save a lot of water resources for users, and is energy-saving, environmentally friendly, and has stable analysis data.
- Three-level authority management, electronic records, electronic labels, and operation traceability inquiry systems.
- The system automatically shuts down after 60 minutes of no operation, which is energy-saving, safe and secure.
- The instrument has a built-in protein coefficient query table for users to read, query and participate in system calculations. When the coefficient=1, the analysis result is "nitrogen content". When the coefficient>1, the analysis result is automatically converted to "protein content" and displayed, stored and printed.
- The titration system uses R, G, and B coaxial light sources and sensors, with a wide color adaptability range and high accuracy.
- The R, G, and B three-color light intensity automatic adjustment system is suitable for the analysis of samples with different concentrations.
- The titration speed can be set arbitrarily from 0.05ml/second to 1.0ml/second, and the minimum titration volume can reach 0.2μL/step.
- The German ILS 25mL injection needle and 0.6mm lead linear motor form a high-precision titration system.
- The internal standard of titrant concentration eliminates the systematic error caused by the difference between human and instrument judgment, and is highly precise, convenient and fast.
- Visible titration cup design makes it convenient for users to observe the titration process and clean it.
- The simultaneous distillation and titration mode can save analysis time and reduce ineffective distillation power consumption.
- Distillation time can be freely set from 10 seconds to 9990 seconds.
- The steam flow rate can be adjusted from 1% to 100% to suit samples of different concentrations.
- The automatic discharge of waste liquid from the digestion tube reduces the labor intensity of operators.
- Shut down and automatically clean the alkali pipeline to prevent pipeline blockage and ensure liquid supply accuracy.
- Data storage can reach 1 million items for users to check.
- 5.7CM automatic paper cutting thermal printer.
- The unique "sample weighing data automatic upload data package" eliminates the need to record and enter the weight of samples one by one, reducing input errors and improving work efficiency.
- The ammonia separator is made of "polyphenylene sulfide" (PPS) plastic, which can be used under high temperature and alkaline working conditions.
- The steam system is made of 304 stainless steel, safe and reliable.
- The cooling system is made of 304 stainless steel, which has fast cooling speed and stable analysis data.
- The leakage protection system ensures operator safety.
- The safety door and safety door alarm system ensure personal safety.
- The digestion tube absence protection system prevents reagents and steam from injuring people.
- Steam system water shortage alarm prompts and shuts down to prevent accidents.
- The steam boiler has over-temperature alarm and shutdown to prevent accidents.
- Steam over-pressure alarm and shutdown to prevent accidents.
- Sample over-temperature alarm and shutdown prevent sample temperature from rising and affecting analysis data.
- Low level alarm in reagent barrel and titration bottle.
- Cooling water flow monitoring prevents insufficient water flow from causing sample loss and affecting analysis results.
- KJA-9870B is equipped with a computer operating system developed by Windows 10, which can automatically generate inspection reports and other network services, and comes standard with a 27-inch computer.
