Automatic Kjeldahl Analyzer, KJA-9870
Description
- 7-inch color touch screen, simple and easy to operate.
- Three-level authority management, electronic records, electronic labels, and operation traceability inquiry system
- 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.
- Visible titration cup design makes it convenient for users to observe the titration process and clean it.
- Distillation time can be freely set from 10 seconds to 9990 seconds.
- Data storage can reach 1 million items for users to check.
- 7CM automatic paper cutting thermal printer.
- 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.
