The ATN-2000 Nitrogen Determinator (also known as a Protein Analyzer) is a product designed and manufactured in accordance with specific customer usage requirements and the national standard Kjeldahl nitrogen determination method. It is primarily used to detect the content of ammonia nitrogen, protein nitrogen, and other components in various samples such as grains, food products, dairy products, beverages, feed, soil, water, pharmaceuticals, sediments, and chemicals. The testing methods comply with national standards, AOAC, ISO, and other relevant specifications.
Product Specification
Product Features：
- The control system features a 7-inch color touch screen with Chinese-English language conversion, ensuring simple and easy operation.
- It includes a three-level permission management system, electronic record-keeping, electronic labeling, and operation traceability query system that comply with relevant certification requirements.
- The dynamic sensing system can automatically shut down or turn off the screen based on operation time intervals to save energy and reduce maintenance.
- The protein content is automatically calculated, displayed, stored, and printed.
- The instrument comes with a free built-in protein coefficient lookup table that updates according to actual conditions; users can review, query, and participate in system calculations.
- The titration system employs R, G, B coaxial light sources and sensors, offering a wide color adaptation range and high precision.
- The RGB three-color light source automatic color recognition system is suitable for analyzing samples of different concentrations.
- The titration speed can be set arbitrarily from 0.05 ml/second to 1.0 ml/second, with a minimum titration volume of 0.2 ul per step.
- A high-precision titration system is composed of German ILS 25mL injection syringes and linear motors with a 0.6mm lead screw.
- The titration cup is exposed for easy observation of the titration process and cleaning.
- The distillation time can be set freely from 10 seconds to 9990 seconds. Up to 1,000,000 data entries can be stored for user review. A 5.7CM automatic paper-cut thermal printer is included. The steam system is made of 304 stainless steel, ensuring safety and reliability.
- The cooler is also made of 304 stainless steel, providing rapid cooling and stable analytical data. A leakage protection system ensures operator safety.
- Safety doors and safety door alarm systems guarantee personal safety.
- A sample tube absence protection system prevents injury from reagents and steam.
- The steam system includes low-water level alarms, shutdowns, and other features to prevent accidents.
- The steam pot has over-temperature alarms and shutdowns to prevent accidents.
