Automatic Nitrogen Analyzer NKB3200

The NKB3200 Automatic Nitrogen Analyzer is a state-of-the-art analytical instrument designed for precise determination of nitrogen or protein content using the classic Kjeldahl method. Featuring fully automatic operation, it is equipped with a high-resolution touch screen for easy parameter settings and intuitive program control. The system automates the entire distillation process—acid addition, dilution, alkali addition, and distillation—completing each step with high efficiency and automatically stopping with an alert upon completion.

Built from durable ABS engineering plastic, the NKB3200 is resistant to strong acids and alkalis, ensuring long-lasting performance in demanding laboratory environments. Its safe and ergonomic digestion tube handling mechanism adds another layer of operational convenience. With rapid testing speed, high sample recovery, and accurate results, the analyzer complies with both national and international testing standards.

The NKB3200 is widely applicable across food and beverage industries, pharmaceuticals, agriculture, mining, environmental science, and chemical manufacturing. It is especially suitable for continuous operations in quality control laboratories, research institutions, universities, environmental monitoring centers, and more. In addition to nitrogen and protein analysis, the instrument can measure other compounds such as volatile basic nitrogen, volatile fatty acids, ammonia, sulfur dioxide, formaldehyde, cyanide, and ethanol.

Designed for stable and reliable performance under various working conditions, the NKB3200 offers exceptional value in terms of precision, automation, and operational safety—making it an essential tool for modern analytical laboratories.
